Battery condition affecting A/C

[gapv7777]

is it possible that a battery that's nearing its useful life can have an effect the A/C system? Freon pressure is ok. there are no leaks, pero walang lamig. any inputs?

I don't think the battery has got to do with your aircon problem. Kung lamig ang pinaguusapan, at ok naman ang freon. There's one part in your aircon system that is clogging up. Either the dryer unit needs replacement or your evaporator/cooling coils needs change.

Batteries can be tested at any battery sales outlet depending on what brand you are currently using. Best of all it's free of charge. Yes, literally free charging too if needed.

sir ungas,

pano naman yung sa pa-iba-ibang speed ng blower?
pag kasi nakatigil medyo mabagal ang ikot ng blower lalo na pag gabi. bukas pa ang ilaw at ibang accessories.

tapos pag umandar parang may boost bumibilis ang ikot ng blower tsaka lumiliwanag yung ilaw sa gauges.

ngapala kakagawa lang ng alternator...pinaltan IC REG tsaka rectifier.

benchph1::: Probable cause, your aircon blower motor is sucking too much current or neither one of your electricals is. Its draining power directly from your battery which should not happen in the first place.

Kaya lumalakas ang ikot ng blower and other accessories alternator is doing its job. You can be sure of that the alternator is functioning well. Check the alternator belt, baka po ito ang maluwag kaya humihina pag minor ang makina. Higpitan po ng kaunti hanggang sa hindi na pumapalag ang belt.

Also check
battery fluid level - baka kulang ng distilled water.

battery terminal connections - baka maluwag oh kaya corroded yung connections.

Alternator bracket - baka maluwag yung belt dahil di nahigpitan yung bracket bolt.

Battery voltage (engine off or engine running with headlights, A/C running) - if it goes below 13 while running the battery may need replacement.
