I believe there is a expansion valve located on the back part of the air conditioner on the back right side i believe that could be the problem. I think if I am understanding you correctly, your back air is not as cool as it should be or not cold at all. Might want to check this. If I am not understanding you correctly please let me know again what your problem is.

99 chevy suburban a/c cools up front blows warm out back.


thermastatic expansion vavle in the rear evaporator. If you are familiar and comfortable working on chevy's - Replace the vavle located on the high side line on the rear evaporator. You have to pull the right rear quarter panel. Remove rear evaporator case on bolt valve and replace vavle. Reinstall and charge the system.

97 suburban rear a/c doesnt get cold but front works great


the expansion valve is in the rear ac housing and it is bolted directly to the rear evaporator. it is an actual expansion valve and not an orifice tube. the part is about $45. the interior on the passenger side has to come out along with the entire rear ac sytem.

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.

I can't find the rear ac expansion valve on my 95 chevy suburban?


Remove two trim panels from just inside back window and just inside rear side door passenger side. They run down from the head liner. Remove seat belt bolt ( TORX HEAD ) also. Remove lower half of trim from just inside rear side door. You should see screws holding weel cover in place. The top under glass just lifts up slightly to remove entire cover. Just a few more screws and you can hinge the top cover of the duct and fan. You will now see the top half of the rear condenser and if you look down beside it you will see the expansion valve. This about as close as you will get to changing the valve though because the freon lines running to the condenser will be stuck so solidly you would have to destroy the lines on either side of the nut to seperate them. You cannot reach the valve without lifting the condenser from its tray and you cannot lift the condenser without removing the lines from it!!! Good luck!!!
