Don't waste your money on unnecessary sources and unwanted repairs. Get this manual online at www.reliable-store.com and get complete guide on whether to repair or not, service it, and how to repair etc

neither of those so run the fault codes to determine which servo/ solenoid has a problem The oil will be hot as operating temp is up to 250 C

Sometimes these radios have what is called a logic lock up. First thing to try is to remove BOTH positive and negative cables from the battery. Then while holding both cables away from the battery, touch the metal ends of the cables together and hold for 20 seconds. This will usually reset locked electronic modules. Hook them back up to the battery and try radio.

Probably a problem with the abs system, a sensor more than likely.

What engine is in it?

Are there any lights on? Sometimes if the parking brake is applied it will ring as a warning.

You need to replace the pig tail connector for the blower resistor. The contacts corrode/burn and will take out the new resistor. The actuator motor needs to be cycled through all modes to "learn" where it is.

renew the alternator .a diode has failed or the regulator .

difficult one this ,without doing the tests myself its difficult -? slow cranking is either a iffy battery ,or too small for the current draw ,failing which its the windings on the starter motor ? now if as you say these have been checked then only one thing left and thats to renew or fit another one to double up so to speak and the earth strap from chassis to engine but i would be inclined to fit another cable from battery negative to the engine direct and see what happens ,

There is no fuse. The windows use a circuit breaker that rests automatically. If the window isn't working, it most likely has a bad motor or switch.

Sounds like you have something broken in the transfer case. Two wheel drive is transmission to rear end. 4x4 mode engages the transfer case, possible broken tooth on a gear, or bad synchronizers

DONT CUT ANY. Get an adapter from car toys or amazon etc. IF you do cut it, make sure you leave room to put it back on. The Chevrolet uses the radio for onstar and body information and you are in trouble if you make a mistake

dont quote me here but i think you may need a new computer for the climate control ? bit hot though isnt it if set to 90?C

Look for broken or corroded wiring in the door, especially where the cable goes from the body to the door. You will probably have to remove the door's interior trim panel for testing and inspection. Visual: a wire with a nick in the insulation surrounded by a greenish stain is probably corroded through. The wire would have to be cut and spliced at that point. Use an automotive grade self-sealing or heat shrink ene-to-end splice, or put heat shrink tubing on the wire, solder the splice, then shrink the tubing over it. If the wire is part of a wire bundle, tape or zip-tie the splice to the rest of the bundle, other wise secure the cable to a support (away from possible contact with moving parts!) at or near the splice. If the door or the frame around the door is heavily rusted, you may have a bad ground connection. Electrical: use a voltmeter or 12v tester to check for power in the door. Check the wiring to the lock and window switches first (especially red or pink). If you don't find any that read at or near the battery voltage with the vehicle accessories turned on (driver's door working), then you know it's a wiring problem. Measure voltage between device connector terminals and a good frame ground point (there may not be any power at the window or lock motors unless the corresponding switch is activated).

Have you tried jacking up the front end and shaking your wheels back and forth if there is any movement at all you have a wheel assembly going out
