1997 GMC Jimmy No dash lights

  • 1997 GMC JIMMY
  • 6 CYL
  • 4WD
  • 175,000 MILES
About 2 weeks ago I noticed that the dash/gauge lights where no longer working. I also noticed that it was not dinging when I left the key in the ignition with the door open.

I have checked the fuse (all the fuses actually) and all of them are fine. I swapped the fuse for the lights with another one just incase and still got nothing.

The other interior lights (mirror and celling lights) and the exterior lights work fine.

Any ideas?
Do you
have the same problem?

Malfunction indicator lamp (MIL) on, trans stuck in 2nd or 3rd gear, instrument cluster inoperative (diagnose & replace ignition switch if necc). See bulletin #01-07-30-002. Techs in field report IGN switch failure is common & may cause multiple symptoms with trans, IPC or other IGN feed circuits. (DTCs) P0740, P0753, P0758, P0785, P1860 may be set.

Most likely cause of this condition may be a loss of power to the transmission on circuit 1020.

To verify, with the ignition switch in the run position, test for battery voltage at the appropriate fuse listed below.

1997 s/t trans 24
1998-2003 s/t (old style) cluster 11
2002-2003 s/t (new style) ignition 0
1997-2000 c/k (old style) trans 20
1999-2003 c/k (new style) ignition 0
1997-2002 g-van trans 20
2003 g, h-van ignition 0
2003 H2 ignition 0
After IGN switch replacement, VTD (theft deterrent) relearn must be performed
Also, GM has a bulliten out about thier connectors, you may need to have a look at the cluster connectors and pins, ceck for bent or pushed out pins in the plugs. Perform a relearn on the key first, maight save some work.
Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it
Was this
