Question about 2000 GMC Sierra
When I get driver side reset the passenger side goes hot
Posted by Anonymous on
I had this happen on my 2004 also. I have the climate zone control module that allows for adjustment for driver or passenger temps. I had to cycle between hot and cold on the passenger side and switch it between defrost and feet, then power off everything for a long period of time using the power button on the control, this finally got the solenoid to become unstuck. If that doesn't work then you have to get into the heater/air ducts under passenger side, which is difficult, to manually unstick or replace the locked solenoid.

I had the same problem in my wife's 2003 Yukon Denali. The power seats and passengers side window wouldn't work. Turned out to be a blown Buss Type fuse in the Underhood Fuse Block. It is the one marked MBEC 1 50amp. Hard to tell if the are blown so look very carefully. Should look like a hoop with two shiny solderlooking bubbles on either side. On my blown fuse, it caught my attention because it looked like the solder was missing and I had to look very closely to see the bottom of the "hoop" was open. They are very hard to remove and must be pulled straight up.
This type of fuse looks like a red square with a clear plastic top showing the fuse link under the plastic. On my vehicle it is on the top row second one from the left.

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Remove the clips and screws securing the old window to the arm and slide it out through the top of the door (may need to be maneuvered out)

Probably the left temp actuator. The wires in the right I/P junction block could have poor tension also, but it's usually the temp actuator.

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."
