Does anyone have any Idea what could cause an intermitent problem,
sometimes , just sometimes when the truck or outside temp is down the
speedometer and tach quit working and a check guages light comes on,
also when this happens the light on the steering colum showing the gear
it's in goes stops working. I did recently replace the cable for the
shifter and didnt have it in neutral when I conected it so it doesent
go into low 1, however it does shift thru all the gears. the gartage
said the cable wouldnt have anything to do with the problem though..
Sounds similar to the problem I had with my 95 K1500. I had a broken connector
in the ignition switch wiring harness. The connector broke due to years of
flexing the tilt steering wheel. Try to generate this issue by running the
engine & tilting the wheel. This is assuming you have tilt wheel of course...
I have a similar problem in my '90 k1500. The speedometer dial randomly
drops off to 0 and after it runs like that for a few minutes i get the
Check Engine light, which stays lit, doesn't blink. If i smack the top
of the dash the dial usually pops right back up and the light soon goes
off as long as it doesn't drop off again. I had removed the gauge
cluster and cleaned the connection but it still happens. I think I'm
gonna have to open up the cluster and see if theres a loose connection
I'm not sure exactly whats happening but if I'm not watching the
speedo and the dial drops, I know its happened because I can actually
feel it when I'm driving, it's like the gas pedal let up just a tad.
Still drives ok but something doesn't feel right. Like the computer goes
into some other mode.
