AC fuse gets blown

[donald22]

hi bigla nalang po nawala ang lamig ang hangin na lumalabas sa ac ko. as i check the fuse box sa engine compartment putol yung 10a fuse ng ac so i replaced it with a spare but after turning it on again blown out na naman. bakit po ganun anong prob? baka naman anyone could help

Have the magnetic clutch of the A/C compressor checked. Chances are it is already shorted and needed replacing or rewinding.

make, model, year of manufacture and mileage?

unable to decipher vehicle make or country of origin. but, the most common magnetic clutch coils have about 1 ohm of resistance. hence, current=voltage divided by resistance (12 volts divided by 1 ohm gives you 12 amps, higher than 10 amps fuse you had. the fuse could be protecting the airconditioning amplifier. the condenser blower uses 15 amps fuse, the evaporator blower uses 15 amps

OT: sir jick what is an aircon amplifier?

TIA

it is an electronic module or microprocessor taking inputs as ambient temperature, engine speed, throttle position, coolant temperature, engine rpm, cabin temperature and high pressure switch/ low pressure switch and outputs as magnetic clutch relay, condenser fan relay, some inputs or outputs are not included. some are more complex. in some systems called climate control, the system is more complicated

Thanks for the brief answer sir jick.

so jick you mean i should put there a fuse with a higher amp? a 15 or 20 amp? but why all of a sudden do it need a higher amp fuse if thats the case?

[OTEP]

Magnetic coil is a good bet here.

Dont use a higher amp fuse. You will potentially burn something if you do that.

Have your A/C system checked, mainly the magnetic coil of the aircon compressor.

still not sure of the model. what is the engine size? what is this car in the u.s. market? there is hyundai accent that uses 10 amp fuse for the a/c clutch. try replacing the fuse with a self resetting circuit breaker of 10 amps and by process of elimination, unplug a/c electrical components until the circuit breaker stops clicking. what are the conditions that have to be met immediately causing the fuse to blow?

not imported to north america. the last vehicle with 1.3l engine imported was the suzuki forsa (chevy sprint) in the '90's. peole who bought this car were told to stay off the freeways.

i see, do you have any idea how much it will cost if thats the case? narerepair ba yun or replacement?

[donald22]

out of curiosity i tried it with a 15 amp fuse and it worked my ac is blowing cold air again. but i follow mr ghosthunters advise baka mamaya may masunong pa na wiring or whatever lalo lalaki gastos.

Both. Assuming it's the coil, you can have it repaired but rewinding will take time (few hours).

Best to canvass both options to see which is more "acceptible" to you.

donald, this should help. same thing happened to my kia picanto, 06 model around 34k kilometers. 10 amp fuse blew, changed it and it worked for 2 weeks. then it blew again. i repeatedly changed fuses even using a 15 amp one. all of them blew.

took the car to sir joel at ceejay's and as i suspected it was the magnetic coil. at first they wanted to take down the whole compressor but i insisted that they just yank out the clutch. they were able to do so and after around 3 hours (including rewinding since no replacement was available) aircon was ok. oh, and it cost me just a bit over a thousand pesos.

AFAIK, the getz and picanto share the same compressor make. HTH
