Top 10 1992 GMC Sierra Questions & Answers

First thing unhook positive battery cable, unhook main cable on starter selanoid and small wire on selanoid (there may be 2 small wires) There may be a bracket on front of starter that has to be removed, and then the 2 main bolts that hold it to engine block and it should come out.

I pulled this from another web site
"The AC clutch relay is located inside the cab on a metal bracket that is easiest to see when you remove the glove box compartment.

The relay is on a metal bracket bolted to the top of the plastic air box, forward and to the center of the dash from glove box.

There are three relays in a row on that bracket. The AC clutch relay is the end one closest to the driver’s side."

You remove any of the trim that is contacting the headliner,remove light in the center,remove visors and any hooks that are there to hang things on ,Most of your trim has push in retainers handles and hooks,seat belts should have screws inthem.

Bad fuel, bad air filter,PVC valve, EGR valve

PULL THE SPEEDOMETER DRIVEN GEAR OUT OF THE TRANSMISSION, IF THE GEAR IS WORN REPLACE IT, IT WILL HAVE A CONCAVE APPEARANCE ACROSS THE FACE OF THE GEAR.

Hi!!
Here is where the bleeder screw is on the SLAVE/SECONDARY cylinder and the instructions to bleed the system.
Hydraulic System GMC SIERRA 1988-95 Models

• Fill the clutch master cylinder with the proper grade and type fluid. Raise and support the vehicle safely.
• Remove the slave cylinder retaining bolts. Hold the cylinder at about 45° angle with the bleeder at the highest point.
• Have and assistant fully depress the clutch pedal. Open the bleeder screw. Repeat until all air is expelled from the system.
• Be sure that the fluid level remains full in the clutch master cylinder throughout the bleeding procedure.
• Install the slave cylinder.

Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

I would say the problem is inside the radio itself. I have no idea if anyone repairs these units anymore or if any good used ones are available.

does it turn over or does it do nothing at all

The brake light switch can prevent the cruise from working.
On the cars there is a 5amp cruise fuse so I would think there is one for trucks too.
You may have to get a shop manual to get the diagrams to check the circuits and have a test procedure.
