No running lights & no dash lights - 1997 GMC Suburban

fuses blow because of dead shorts or excess current draw
to blow a 15 amp fuse indicates a dead short
by disconnecting the rear lights , the problem is in something else you have replaced
could be a problem in the head light wiring

All dash lights should light with the key on/engine off

ALL dash lights should go out when the engine is running

If you have ANY Light lite,you have a possible system failure
& check for codes,diagnose them,component test & resolve

You can google your codes or Stabilitrac & read up

Read your owners manual

I would say its probably a short or a ground problem at the turn switch or a wire in that area. you need a test light and probably a multi meater and some nohow a ground or wireing problem can even drive a master teck crasy.

Won't run over 5 MPH after STARTING ?

( Cranking is the starter turning the motor over )

Is there a check light on the dash?

Is it in Fail Safe & a light on dash,if so I would
be looking into failed ignition coils

If it starts & runs at all,not likely the CPS you asked about

Have you had it checked for codes ?
Do that & correct code related issues first.

THE DASH LIGHTS ARE USUALLY CONTROLLED BY A SMALL THUMB WHEEL NEAR THE HEADLIGHT SWITCH ON THE DASH. THAT IS A RHEOSTAT, THAT MAKES THE DASH LIGHTS BRIGHT & DIM. REPLACE OR BYPASS IT.

Look for filiment issues in the taillights. perhaps just install new ones. Also check for grounds that are weak there. Either case can have current come back through the running light circuit and fire off the dash lights and other running lights.

the cd players almost never work in those so i doubt thats related. as far as dash and running light check your accessory fuse in the pana. The are linked. If the fuse blows it all stops working. Usually a 15 or 20 amp fuse

In my 1997 chevy S-10 The gauge dash lights wont turn on when I flip the switch but both turn signals come on solid instead?!!? please help

You have obviously damaged neighboring wiring in the fuse panel. The reason the dash lights and radio is pulsing is because of feedback.

I looked in a Haynes manual and it showed a 20 amp fuse controlling the the dash/ taillights. I t sould be in the fuse block under the the driver's side dash. If you have your owners manual, there should be a fuse locator diagrahm to help you locate the right 20 amp fuse. Remember usually when your dash lights are out so are your tail lights.
