Hi All,
Thought I'd reach out to the forum and see if anyone has had similar problems on their truck and suggestions on how to fix them.
I drive a 1996 GMC Yukon 2 door, 450,000 miles.
The most recent issue is the brakes lights being on without pressing the brake pedal. And while this issue is happening the right directional turns on, makes a horrible buzzing sound but does not blink. After the truck warms up (I am in New England and not sure if this is air temperature related and not exactly sure at what point this issue goes away) the brake light will go off and the blinker will work as normal.
About a year ago I replaced the directional stick.
Another issue is fan speed control knob. It only works on the high speed, which I have read here on the forum is the default setting when the others do not work. This first happened about two years ago. I replaced the blower motor, the resistor and the.....none of which fixed the problem. Then I replaced the whole AC control panel. That did fix the problem. The fan worked fine for a year and now, again, the fan only works on high speed.
It seems to me that it is not the control panel that is the problem. Rather something is causing the fan speed knob to fail.
Any ideas on what could cause the fan speed knob to fail?
Another issue is the passenger side headlight. It works, but is rather dim. I have read somewhere that is could be a bad ground. But I am not sure where the ground is located to clean it up.
Is it normal for the fan speed to vary with the engine rpms?
One other issue I'll touch on quickly, and not sure it is an electrical issue. I tried to turn my truck off last week but the truck did not stop running. Key was out and I tried putting the key back in a few times with no luck.
By the time I got home it did turn off. It only happened once so far.
Any suggestions on that fix? And if it does happen again how would I get the engine to stop running???
Possible a worn out key? Or maybe the truck need a new ignition lock cylinder?
Much thanks!
Mike
