Where is the rear condensor located on a 1999 Suburban I am getting a drip behind the rear passenger side wheel but it doesnt smell like gas?
On my 1996 Suburban which is pretty much the same as you're 99. The rear condensor is located at the back door. When you open the door the shelf on the right side is removable. You will see the slots at the end of the carpeted area. That is where the rear condensor is.
Why would a 1994 cavalier wagon keep getting wet on the passenger rear floor with no visible sign of a leak top or bottom?
The Drivers Door Module or Passenger Door Module on a 2003 suburban is also known as the "window / door lock" switch. These modules are located on each respective door, i.e. driver side door or passenger side door. It is the module that has the door lock/unlock switch and window up/down switch. Hope this helps...
Chevrolet discontinued cabin air filters on the Suburban in 2003. (However, the C.A.F. on a 99-02 is located under the dash on the passenger side. There is a black plastic cover that will need to be partially removed. After that, you will see the blower motor housing/ducting. On this you will see a plastic panel about 7" long by 2" wide. Remove the two gold colored screws and "viola" there are the two C.A.F.s.)
If its a single evaporator unit (front air only). then it is probably located in the condensor. If it is a dual unit (front and back), the front orfice tube will probably be after the "Y" in the compressor high pressure line, and prior to the accumulator. The rear unit does not use an orifice, but rather a Thermal expansion valve.
It is located under the hood approximately in the middle of the vehicle right up front BEHIND the A/C condensor coil. What you see when looking at the very front of a vehicle (with air conditioning) behind the grill is the condensor. The radiator is directly behind that and has a metal cap on it; not to be missed.
