Here is the diagram for your truck, there is a fuse and a brake switch, if the rear turn signals work this means the fuse is good. Most failures are the fuse or brake switch, see second diagram (#4) The brake circuit actually goes through the turn signal switch (not shown in diagram), which in rare cases a faulty signal switch can cause the brake lights to ...

The Sirius/XM receiver is built into the antenna just above the driver on the roof of the cab. It looks like this: To gain access to the wiring on it, you have to pull the hood liner down.

The center high-mount stop light is fed directly from the brake light switch, but the other two, since they double up as directional indicators, are fed through the multifunction switch, first through the hazard switch, then to the 'off' position of the indicator switch. (I don't remember where this schematic came from, and the exact details may not be ...

This is a pretty common malady for the 4L60e transmission in GM trucks of this model. IIRC, the problem is most likely the sun shell is broken. If you were a mile away, I'd suggest you could drive it. Since you are talking 20 miles, the fastest you could drive it (reasonably) without causing issues for your engine would be about 20mph. That would mean it ...

I realize that this is a very late response, but the 93mph limit is due to the 8810 RPM limit of the motor, not an otherwise safety demanded limit. I doubt anyone will be able to bypass this, nor would it be safe to do so. Computers in the cars are far more integrated these days, we can't just hack them like we used to.

The ECU controls the starter on this vehicle, moving the key to start initiates a start sequence - which can continue after the key is released, and the key being in or moved to start is ignored once the engine starts, so it's not the switch. Most likely the starter motor is damaged, either the solenoid is sticking mechanically, or the contacts are welding ...

Yes, the starter could catch fire or it could be completely destroyed if it remains engaged while the engine is running. Check to make sure that the ignition key is returning by itself to the RUN position after you release the key from the START position. If it is not, turn the key back to RUN after the engine starts, and the starter should disengage. In ...

Some vehicles have a coolant temp sensor that adjusts how rich the fuel mixture is depending on temperature. I have heard that disconnecting the sensor simulates a cold start. You might as well give this a shot. If it starts with the sensor unplugged, then you probably have a bad sensor.

It sure sounds as though your engine overheated. Possibly due to air in the system, a stuck thermostat, or something that resolved itself as you continued to drive. But the damage may have already been done and the white smoke, which I assume was water being drawn into the combustion chamber, indicates that your cylinder head may have warped. This ...

1) CRC makes an QD Electrical Contact Cleaner. It's available at most auto parts stores. This will work fine for cleaning electrical terminals. I like to use that and a brass brush to clean terminals. 2) You can usually buy a starter rebuild kit. Check RockAuto.com. Up to use to decide if the price/effort is worth the hassle or if replacing the starter ...

One thing you didn't mention was the coolant hoses. If they are are blocked or kinked in any way that would cause overheating. Is the coolant mixed to the correct concentration and the right quantity ? When changing everything in the cooling system you most times get air pockets in the cooling jacket that need to be bled out. These air pockets cause hot ...

Used it a lot back in the early 70's, seemed to be common knowledge in all the Dealerships and was Very effective at removing carbon deposits on the pistons and cyl. Head areas.
