1997 GMC Sierra Ignition Switch Replacement

How do you replace the ignition switch in a 1997 GMC Sierra Truck ?

Answer · Mar 15, 2009

take off the cover on the top and bottom of the steering column just behind the wheel. pop the tilt lever out simply just by grabbing it and give it a good tug. then once you have the new switch and you get in there your going to need an inverted torx socket to remove the small bolts that hold the switch to the column. do not move the gear on the new switch make sure it lines up exactly as the old one did!!!!!!!!!!!!

1996 GMC Sierra Heater blower motor only works on high speed. How do you change resistor?

Answer · Jan 24, 2011

The blower motor resistor is located within a foot of the blower motor in the duct that the blower motor blows into. The resistor is actually cooled off by the blower motor blowing across it. It has a wire harness that connects it to motor & fan switch. It is held in place by 2-4 retaining screws. Disconnect wire harness,unscrew retaining screws then lift out. Reverse order to install.

2005 GMC ENVOY Gear Shifter won't move,why and how do I fix the problem?

Answer · May 24, 2014

I am assuming the shifter will not move out of Park (you don't mention it). The shift interlock is not working. Thing you can do is turn ignition key little, but just before ignition comes on, and try to move shifter to N. At this stage you can start the engine and shift to D. This is a temporary solution to allow you drive the vehicle to a repair facility. If you are successful, it is the interlock solenoid that needs to be checked out.
