Re: Ac not as cold when car warms up

Sorry for the late reply. after researching the past few days, ive come to the conclusion that there was air in the system causing the gauges to show a good reading but still actually be undercharged. So i thought about evacuating and recharging the system myself. Ive run out of funds to buy a vacuu...

Re: Ac not as cold when car warms up

The problem also progressively gets worse the longer you run the car. I got stuck in stand still traffic for nearly 30 mins and the cooling was basically non existent. Edit: And it got cold again when the traffic started moving. This seems to indicate a bad fan clutch to me. If your vehicle (you di...

Re: Ac not as cold when car warms up

I forgot to mention that the problem appeared a few days after i had my evaporator replaced with a "new used" one. I brought it back to the shop but the ac guy without a thermometer told me the pressures are fine its cold. The problem also progressively gets worse the longer you run the ca...

I'd like to but then i wouldnt have a way to control the temp when its cold outside. Its very humid here so it isnt comfortable using the car with ac off, specially when its raining.
