Rear heater blower continues to run even when the ignition is off.

SOURCE: 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.

SOURCE: the rear a/c on my 1996 gmc suburban is blowing

the problem is in the rear expansion valve. this valve is located at the rear evaporator core. i am assuming the freon level has been checked and is ok. this is a common problem with these vehicles. hope this helps!!

SOURCE: My rear AC and Heat is not working in my 2001Suburban

start by check all fuses, then check for power at rear blower.if fuses are good and you have power then may have bad blower,if no power and fuses are good then may have bad resistor. hope this helps good luck.

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!!!

Suburban rear blower motor - continuously running


hmmm as little as i know about these american vehicles i would suggest that you have a feed to the blower motor and the cut off is in the negative return via the control switch ,or a power relay is stuck on sorry to be not a lot of help here but if i had the vehicle in front of me with my meter in hand i would soon work it out ,my XJ6 has the former system and some have the later system where the power goes through a resistor then the motor but later types have a circuit board thats all micro chip controlled and it could be a switching tranistor has broken down and its melted inside and allowing the current to flow all the time ,

Low coolant suburban


Where is your coolant going is the biggest problem you have to fix first. You may want to look at the water pump too.

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

The rear a/c blower keeps running after the engine is off on my 2003 Suburban.


Replace your relay to your rear blower motor and inspect your wire harness. Common for the harness to melt or the relay to melt causing it to short and keeping the blower motor to run.
Thank you for using Fixya, good luck.

No rear heat


There is a seperate heater core for the back of the Suburban. It is located behind the right rear interior quarter panel. You have to pull everything back there the heck apart to get to it. The blower motor is located in the same area, so if you should be having any issues with it, plan on doing them both at the same time. Also, you have to drain the whole coolant system, so if you need to do anything with the front heater core (doesn't sound like you do), plan on doing that at the same time too. Good luck!
