My reverse lights, brake lightand turn signals do not work. Running lights do. My 3rd brake light(on the cab) does work though. Fuses are good, relay seems good, new tail light bulbs and circuit boards still no fix.

1988-1998 GMC Pickup: How can I fix or replace dash gauges?

Sun, 07 Sep 2025 12:09:27 -0700

How can I fix or replace dash gauges?

@oldturkey03 Yeah it's a 94 GMC Sierra k1500 .

Seems oil pressure gauge(which I changed few years ago/failing to start) started too be erratic, year later or so the temp gauge goes rt too hot when running a few seconds, (pump replaced years ago, coolant good and no overheat). I changed sensors/wires (two), cleaned MaP sensor, checked grounds, found one broken but had no effect when connected. Didn't replace thermostat yet but have it, my guru says it's likely gauges going, there's motors in them that die off, short of tearing things apart thus breaking clips etc, what else is good or how to take out the cluster and replace it or gauges etc on the very cheap low expense end.

Seems The air/fuel mixture due pcm being told it's running hot (which happened years ago w broker fan belt) causes choking when stopped like it's timing is off-rumbling sensation. Worried about damaging worse then already may have driving

1988-1998 GMC Pickup: 1994 Chevy Silverado K1500 transmission not shifting into 2nd gear

Mon, 18 Aug 2025 11:52:56 -0700

My 1994 Chevy Silverado 1500 4 x 4 is having an issue shifting from 1st gear into 2nd gear unless I back off the accelerator at 21 miles an hour then it will shift. Do you know what the cause of this is? Possibly the vacuum modulator?

1988-1998 GMC Pickup: Truck wont go into park

Sun, 04 Aug 2024 17:55:50 -0700

My truck doesn't go into park, it will go into every gear but with you shift it into park it stays in reserve. So basically park is reverse and reverse is reverse. The problem started when i parked onto my driveway which is a 45 degree angle. It was them stuck in reverse and I probably pulled it into a different gear to hard but it went into neutral, reverse and drive but not park?
