Hello all...New to the site..It is great!....
'98 GMC K1500, 5.7. Experienced during hot weather not able to shift out of park. Other trouble: A/C compressor not working, blower only works on high. cruise intermittent, dash lights for radio buttons/CD out.
Replaced brake light switch, BTSI solenoid, brake relay in relay center, ignition switch, multi switch assembly. Tumbler w/ new keys coded by dealer and ran relearn procedure. All fuses checked good in relay center and I/P fuse block.
Research tells me that the orange wire should be hot at all times to brake switch....No power to this pin at all in connector. White wire shows hot. Key in off position. (Continuity test light) Traced orange to splice before brake switch, looks good.
After ignition switch replacement, with engine running, selector would move out of Park, but no brake lights or third brake light. Now it will not move out of Park again.
All lights, turn signals and interior lights work....no brake lights.
Going to start short testing w/ circuit breaker short finder and test light, but w/ no fuses blown not sure where to start other than orange wire from fuse relay and I/P block. Will check red boot on positive lead at battery for good connection at outset.
Of course the dash is disassembled, Do all of the components need to be plugged in (head light switch, 4WD selector, ignition switch, etc.) to start looking for short?
Hopefully someone has tackled this issue before and can save me a little time, expense..and the white bass will be running soon.
Thanks,
Tom
