You are going to need to use a multimeter and have a professional test the relay voltages. This should probably only take an hour, make sure they have the proper electrical schematic for your vehicle year make and model.

Front & rear ac is "ok" on high RPM but on low does not cool at all,I'just change compresor. Is it any filter in those lines,maby.


Theres no filter for the rear a/c lines, the problem is the lines themselves are too long. On low speed, by the time the cool air reaches the rear vents, its already warming up again.

1999 Suburban, A/C on warm air from front vents, cold air in rear


The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.

Did you hear a little rythmic squeaking noise under the dash by the driver's right knee? Is the noise now gone? There is a little oscillating air flow gate there that often goes bad...I can't remember the name of the part, for the life of me, but the dealer has them.

Rear ac on 94 surburban blows warm, front is cold. Is there only one orifice on the dual air system.


The rear air has an expansion valve in the rear of the cargo area right next to the rear evaporator. There is no orifice or filter between the condenser and the rear expansion valve so if there is any debris in the line it will clog the expansion valve. The orifice under the hood is only in the front circuit so if the front is cooling and the rear is not, most likely the expansion valve is clogged and needs to be replaced.

There is a factory service bulletin on how to r&r the expansion valve. It requires some cutting since they did not design it to be replaced. Part of the service bulletin is adding an inline filter at the outlet of the condenser before the front and rear flows divide. That will keep the rear from clogging up again.

I have a 94 Suburban and I had to do this in about 1998. With the filter I haven't had any problems since.

Rear a/c not blowing cold, front works fine.


you may not have enough refrigerant. a low charge can cause the rear in this dual system to not work for beans. charge with a can of uv and find the leak. fix the leak. evac the system and recharge. i think you take 4 lbs, but check the accumulator sticker. you may want to just change the accum at the same time.

Front aircond. blows warm. Rear air is cold


this is caused by a defective temperature control blend door actuator motor. Don't overhcahrge the system, if one part of dual climate works ok the problem is not the compressor or the system charge
