Aircon problem led to car overheating

[kwekmiester]

Good Day fellow tsikoteers! Just want to ask for advice regarding a big problem I encountered with my Lancer GSR. I'l make this short:
Last week, I had problems with my aircon, parang di na sya lumalamig. Last Sunday, I was in Alabang so I decided to bring my car to Wings West Alabang Motortown to have my aircon looked at. At first they said my aircon needs cleaning and charging of freon so I said OK. An hour later they said the car was OK, I paid my bills and before leaving it seems the aircon was still not fixed so they take a look again at my car. Almost an hour later, parang di nila makita yun problem sa aircon so they decided to create a new relay, I think for the compressor. I asked them "kung OK lang yun" and they said it was OK, it took them another 20-30 mins and they said its now OK. It seems the aircon was working so I initially thought the aircon was fixed.

Sunday evening, I drove from Muntinlupa to Sta. Rosa and found out that the temperature was climbing and a few minutes later my car stopped sa Expressway, my car overheated. Good thing I'm about to exit the Binan/Carmona Tollgate when the engine stopped, and since I bought my car I never had overheating problems with it. I let the engine cool and since malapit na ako sa bahay I decided to drive the car moderately. Was able to get back home and Monday morning I checked the car and naubos na ang tubig ng radiator and Coolant, oil still looks OK. I filled the radiator with water and drive the car to the nearest repair shop here in Sta Rosa. Upon inspection, the major damage only was the water pump, thermostat valve and head gasket, minor repairs were radiator cleaning. I also asked the shop to repair the aircon bec. it seems the problem came from the "relay" that Wings West did. The mechanic told me that the problem indeed came from the aircon relay they did (Wings West) and it seems the compressor weren't going automatic (not sure what that means) and it added load to the car which in turn led to the overheat problems.

My initial concern is, what compensation can I ask with Wings West since they were the cause of the overheating? I think at least, I deserve a refund, what do you guys think?

Compensation? I doubt it...they'll just deny that it was their fault and since pinagalaw mo na sa iba mas meron an sila deniability

I see, thanks for the reply Sir Shadow. I really don't have any choice since I can't bring my car to Alabang, its just too far and I'm afraid that I'll overheat on the way since I'll be coming from Sta. Rosa. How about a refund? They didn't fixed the aircon and actually brought me more problems

[victorevolution]

bring an action sa small claims court, here you no longer need a lawyer

first ask for a refund pag ayaw file ka ng damages sa small claims court

[Syuryuken]

tinignan ba kung bakit naubos ang tubig?

[andrew_28]

sayang naman engine, nag -overheat dahil sa hulaan portion sa wing west.
kung malapit ka sa may asia brewery, meron a/c dun kay cooltime. maayos kausap si dodie.

another case of guess and hope system. try to guess the problem and hope you fixed it
as always, the sequence is concern, cause, correction, confirm.

in short:
1-interview the driver, ask pertinent questions
2-make measurements and digitize results, e.g. engine vacuum in inches of mercury at idle speed, pressure of the suction side at idle speed and at what ambient temperature
3-make adustments, repairs, replace worn out or time change parts, service with the correct fluids
4-make measurements again comparing the before and after results

it's a case of one guy saying the other guy was wrong, with no solid evidence to back it up. i think you'll spend less if you list it under experience costs and pay for the repairs yourself...
ano bang ginawa nung naunang siraniko? kinabit yung auxiliary fan sa compressor? pagpatay ng compressor, patay rin ang aux fan?

Lessons learned na lang Sir. mas maganda stick to the original design at ayusin kung ano yung problem. Hindi yung gagawan ng paraan para tumakbo.

[kwekmiester]

Thanks for the reply guys, first of all just want to update that my car is fixed now. First of all for clarification, di po ako yun gumawa ng sarili kong aircon, ang unang gumawa ng aircon ko is a known shop in Alabang Motortown - Wings West. Since na acquire ko yun sasakyan ko, never sya nag overheat not even when I drive my car to Camsur (9-10 hr drive) a few years ago. Nag overheat lang sya nun last Sunday bec. of the "fix" na ginawa ng Wings West.

The main cause of problem is the relay na ginawa ng "seraniko" ng Wings West. According sa South Rides Sta Rosa (shop na pinagdalhan ko ng sasakyan after mag overheat), di daw nag "automatic" ang compressor because of the relay which led to the overheating. Total cost of repairs due to the overheating cost me around 7k for the Water Pump, Cylinder Head Gasket and Thermostat Valve, no other major damage (Thank Goodness) pero umabot sa 15k+ dahil pinasama ko na ang Radiator Cleaning at Aircon Cleaning & Repair and other minor repairs like Power Window problems etc.

*andrew_28 Asia Brewery, san part po to sir sa Sta Rosa? I'll keep this in mind in case that I'll need future aircon repairs

*victorevolution Thanks for the advice Sir, I'm really planning to ask for refund. In fact tinawagan ko na ang Wings West and they asked me to come over to discuss and take a look at my car, of course I'll ask for a Refund bec. di naman nila nagawa yun sasakyan even though I paid for the service.

The cooling system is seperate from your air conditioning system. Your case is of neglect of your own car.
Since when did you check your coolant level? When was it changed?
What is its service history?
It may even be due to your water pump failure.
What was the condition of the water pump? corroded? Where is the point of leak?

they maybe mechanically or physically seperate or separate but they are closely related. the a/c can cause overheating and overheating of the engine affects the a/c system. some systems for example the korean gm chevy epica, the a/c stops working once the pcm detects abnormal change in the coolant temperature sensor signal like when you forgot to install coolant after engine or a/c repair. as you work more and more on different systems and different makes, you will discover inherent characteristics of different cars.

[dr. d]

my 90s sentra aircon stops cooling when the engine overheats; programmed ecu protection probably.
but an overheating engine does not cause the compressor to get destroyed... the compressor will still compress even if the engine is already melting..
and the explanation from the second shop that you narrated, leaves much to be desired. what did he mean? that the compressor did not stop functioning until it got destroyed? or the compressor did not function? either way, the engine should not have been affected. the compressor could have self-destructed, but this should not affect the engine.
curiouser and curiouser...

So would this apply to PH domestic lancer gsr or Mitsubishi PH domestic models?

*mark_t I think you didn't understand my explanation very well, how can it be neglect of my own car? FYI - Yearly pinapamaintenance ko ang sasakyang ko. Paliwanag ko lang mabuti sir, never ako nagkaproblema with engine overheating ever since na acquire ko ang car ko, and EVERYTHING is OK with my car except the Aircon bago nila gawin sa Wings West. Nag overheat lang sya the same day, I repeat - the same day after ginawa ng Wings West and "fix" sa Aircon ko.

personal experience... when the water pump starts leaking, you can lose all your radiator water within the day.. actually, i lost half of it within an hour of heavy traffic..
is it possible, sir, that due to wear and tear, the water pump started to leak, causing the engine to go hot.. then the ECU saw that the engine was getting too hot, and so caused the aircon to cut out.
might i inquire, did you see the temperature gauge the first time the aircon cut out? was it showing a hotter-than-usual reading?
in my personal experience, the first sign of water leak was the aircon cutting out, and when i looked at my temp gauge, it was hotter than usual.. and when i pulled over and inspected my overflow cannister, it was empty! and when i got to open my radiator cap, the radiator water was not visible. .. and when i poured in some water, it took 2 (or was it 3?) liters to make the water level appear again...
what i am implying sir, is that sometimes, things are not that obvious..

one more possibility.. your auxiliary fan isn't blowing enough air to cool the engine and aircon. time to replace it?

[Jiggs]

The only interconnection of AC to the cooling system is the condenser / radiator fan. Kapag nabusted yung relay or fuse then it will lead to overheating, unless ginalaw nila ang electrical then pwede maging cause yun., but if both fans are operable..AC is not really to blame. Also some are shared drives with the water pumps via serpentine belts...but again obvious din agd yun Kung maputol lumuwag ang belts.

[kwekmiester]

*dr. d and *Jiggs, yes you're both correct as I didn't mentioned that the aux fan had problems as well bec. of the relay they (Wings West) made, hence cooling was insufficient bec. the fans weren't functioning properly. When they created the 'relay fix', they worked on the wiring. The first time they made the relay, the fans didn't worked at all and they have to 'rewire' the relay. Again, before the 'relay fix', my car was perfectly fine, temps are normal. The temp gauge went high the day they fixed the aircon.

I wouldn't accuse Wings West blindly, the fact that my car was running well w/o problems even with the aircon not working already - took me almost a week to get it fixed and drove my car a couple of times, back and forth from Muntinlupa to Sta. Rosa and didn't encountered any overheating whatsoever. When they fixed the aircon on July 14 Sunday morning, that's when problems stated - Sunday Evening I drove from Muntinlupa to Sta Rosa and engine overheated before Binan/Carmona Tollgate. I think its safe to assume that it was Wings West's mechanics fault.

FYI - The main problem with the Aircon was the wiring only. When the shop here in Sta. Rosa fixed the wiring (also removed the 'relay fix' Wings West made), my AC was running great again.

*dr. d Sir I'm pretty sure that I don't have water pump leak, the fact that I was driving my car normally (temps were normal) even with the AC problem almost a week before I took it to Wings West. Also They took more than hour fiddling and supposedly fixing my AC. About 3 mechanics were around my car's engine, they didn't told me that Water Pump was leaking.
