2002 Chevy Tahoe Rear Ac Not Working
I wish I could help you, but I'm watching this post closely. The expansion valve is not bad to do, I would recommend replacing it rather than clean it. And that if it is sticking, then the rear won't get cold air.

rumblefish7304-23-2006, 09:31 PMNot sure if you have figured out your rear heat problem? Now it has 111k miles. gmtech7906-16-2006, 10:34 PMYes, sounds like you have a problem with the expansion valve in the back, it is inside the aux. The last time I had to replace an orifice, my compressor failed and put crud in the lines.

Sorry I don't have a gauge to read high side. Got a plug in the flow back to the heater core somewhere? You can also do all this without removing the rear heater core.
- I wish I could help you, but I'm watching this post closely.
- Is there a fixed orifice plate at the evaporator?
- Hoping it's something as simple as adding some r134.
- Post back pressure readings.
- Both lines at the rear evaporator are warm when I fully load the a/c on max, one is just a bit warmer than the other; unlike the front where the one

- Anybody have any ideas?
- The front is cold as can be, but the rear just feels like outside air.
- Low side at idle 600-700rpm is around 70psi and goes up to 120psi when the compressor cuts out.
But I have a 2001 Tahoe LT and it only has A/C in the rear and doesn't have heat back there. Also, if the second orifice is plugged, what could have plugged it? If the valve is stuck in the closed position, there will be no cold air to the rear. 2003 Suburban Rear Blower Not Working MT-250004-23-2006, 09:46 PMWe need your low and high side pressure readings at idle and at 2000 rpm with both units turned on.
Now it has 111k miles. Suburban Rear Blower Not Working Have you charged it or added gas or done anything to it? Expansion valve or orfice tube or weak compresser or way over charge could cause it. Could my compressor be failing and that's why I threw a belt, even though it spins nicely now and provides cold air up front?
Sorry I don't have a gauge to read high side. 2001 Tahoe Rear Blower Not Working Have not charged this truck since I bought it in Nov 04' with 80k. hvac case. I'm a Dallas-boy...the rear heat is simply a second heater core in the rear, isn't it?

Not too much of a problem in Central Texas, but it is a pain for those 6 days a year when we want it to blow hot air. http://myfreepsd.com/not-working/gas-hob-not-working.html Low side at idle 600-700rpm is around 70psi and goes up to 120psi when the compressor cuts out. paul_k07-28-2016, 01:07 PMCheck this video out http://youtu.be/eFQSiToWkuE RepairPal Get Your Car Fixed Learn About Your Car About RepairPal
The AC system has never been charged before. Rear Ac Not Blowing Cold Air It's cheap. Jay MT-250004-27-2006, 02:42 PMI'll try to hookup gauge tomorrow and read low side at 2000rpm.

If the explosion does not kill you at 500 lbs the freon is at 500 gegrees which could cook you and the freeze what is left when the pressure drops. I cannot find the rear orifice tube.

Because it will be plugged. I traced all the way back from the rear evaporator connections to the compressor. if you are low on r134 the front will work but the rear will not Reply With Quote 04-10-2009,08:25 AM #3 Stranger2 View Profile View Forum Posts View Articles Registered User navigate here Home Forum FAQ Calendar Forum Actions Mark Forums Read Quick Links View Site Leaders Classifieds Vendors #tab_mjk4_219# Forum General Discussion Technical / Maintenance Rear AC not blowing cold Thread: Rear AC
Thanks in advance... http://www.autoacforum.com/ MT rumblefish7304-24-2006, 03:45 AMI'll try to hookup gauge tomorrow and read low side at 2000rpm. Do I have a compressor going like SIDES who said his keeps breaking belts? You will probably get 100's of posts to glean.
If you look at your rear air controls do you have one fan speek knob or three that includes the temperature and floor/ceiling selection? Thanks in advance... there will also be a brass expansion valve(same thing as the front orfice tube) with it. The low pressure side at the accumulator is reading 54 psig.

Does this make sense to anyone? 2002 Yukon - 20" Boss 313 Nitto NT 420S tires McGaughy 2" Spindles in front; Belltech 3" Springs in back with shock extenders 4.8 L You will have to split the air box in the rear of the truck that has the heater core and all the blend doors and there will be a small a/c Definetly need Hi and Lo side readings with a quality gauge set like MT-2500 said.
Now it has 111k miles. The pressure in one can reach 500 lbs or more if something is wrong. All the controls are set to cold for the rear and the blower is operating fine. Cannot find any fittings in back.
Always have a high and low gauge hooked up and watch them with both eyes when you check or recharge a air cond system.
