Hi - looking for a wiring diagram for 2002 S10 4 door blazer.
Having issues with blower motor and power windows on the two right doors.

 

Ask and you shall receive. If you can tell us about the problem you're having, George should be along soon to help you troubleshoot it.

 

THanks !!
I just bought the Blazer and :
- when I turn the heater fan on nothing works at any speed (whether it is on or off I can hear some weird sound by where the blower motor is but only when I turn the car off)
-the main window switch doesn't seem to work at all, and using the individual window switches only the passenger side front and back roll down

 

Lets start with the windows. So none of the 4 window switches on the drivers arm rest work in either direction? What about the other three window switches on the drivers rear and two passenger side windows?


George

 

Yes - none of the 4 switches work. The passenger side front and rear work if I use them on the individual doors. The rear drivers side when using the individual switch on that door did move a tiny bit (so that is likely a separate motor issue).

 

Sounds like either the drivers window switch module has failed or the power/grounds to that module are compromised. Open that door panel and measure the voltage on the dk green wire going into the C1 connector. Then check the quality of the two ground wires both on black also on the C1 connector.

Thanks - will try that tomorrow. Much appreciated.

Now what about the heater/ac? Any suggestions ?No matter what setting it won't blow air. When I turn the car off there is a load buzzing sort of noise that comes from where the blower motor is. That sound happens whether or not I had the controls turned on at all.

 

Manual or automatic AC?

Auto Heating A/c controls

 

Also, NO POWER to the green in the window controller.
