Usually its under the passanger side dash, but when in doubt follow the coolant lines, they should be about an inch around
SOURCE: 2000 GMC Jimmy Power seat stopped working
Left side of the dash, to the right of the IP fuse block. Its a 25 amp circuit breaker, an aluminum cased breaker. CHECK FOR POWER ON THE SEAT SWITCH "A" TERMINAL AND GROUND ON THE "D" TERMINAL. IF YOU HAVE POWER AND GROUND THE SWITCH IS BAD.
Testimonial: "thanks"

Chanses are that little hole will turn into a big hole its only a matter of time, its not that hard, don't be inteminated by it, even if you have never done one before. Chk. the carpet on the pasengers side floor see if its wet, anyhow if you can smell antifreeze thats what it is heater core.

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana
SOURCE: My 2000 GMC Jimmy has been blowing cold air. We
airjoc does not have a clue to your problem, I take you want to have warmer air not cooler ac. check the control system, if you have a vacum system tou may have a leak, if it is controlled by voltage, check the control panel and the control box. Also open the hood, place the heater on high but not on any defrost setting preferrably on just the floor setting. Start the engine and see if the ac compressor is running. If it is, the control panel is bad.
