b14 ac worries

14lover · Postby **14lover** » October 1st, 2012, 7:40 pm

when i put on the ac for the first time for the day, it works ok, then gradually its gets warmer as time goes by when driving, and when i accelerate, the breeze gets cooler and when car stops it gets warmer(changed two compressors already and same thing

) the ac lines are ice cold and everything seems to work good under the hood, however the temperature of breeze through the vents are a different story..what u tuners think is going on with my b14?

Sounds like your evaporator is "freezing up". Is you compressor tripping on and off? If it is the expansion valve on the evaporator could probably be the problem.

You also said the car is idling too slow, does it idle up when you turn on your AC? If not, you could have a problem with the IACV.

when changing that, clean out your throttle body before.

How would one go about cleaning an evaporator?

Take it out and wash it under a pipe. If u pressure wash it, u will damage it.

Pressure washing is what you need. With regular pipe pressure you will not wash properly.
