They have fuses these days, check them.

Also check to make sure the fuses get power with them turned on or the switch could be bad................... but I have seen two bulbs go gad at the same time.

Is the engine getting spark? Did you replace the fuel filter? Are any of the fuel lines twisted or crimped?

Can't see it from the underhood area. Only from under the engine - on passenger side at rear of block.

Chances are you need a new air pump. Very common problem. Expensive for dealer to fix it, but easy if you can do it yourself.

Check for trouble codes. You can get this done free at most car part stores.

If you just need to replace the handle there should be a small allen screw on the shift knob. that will release the knob lift up

If there is a problem with the brake lights the shift interlock will not release the shifter out of park, Until you can fix your lights you can get it out or park by turning the key on(engine not running) shift into nutrel then start the engine, put in drive and away you go.

It raises and lowers your rear air shocks to keep the vehicle level depending on the load it has inside the cargo bay, or amount of passenger weight in the vehicle.

An engine spinning just means your battery is good and starter works. You'll need to find out if you're getting the other things you need. Those being air, fuel, and spark.
For air, take the air filter out of the picture by removing the air flow going to the carb. Try to start the car.
if it doesn't start, for Fuel, try spraying into the carb some starting fluid then try starting the car. Does it run for a little bit with the starting fluid you just sprayed in there? If so, you've probably got a fuel problem.
If the engine still won't start, take one spark plug out and keep the spark plug wire attached to it. Make sure the spark plug is touching metal so it's grouned electrically, like laying against the engine block. Don't hold the spark plug because you can get a good shock if you hold it wrong. Just lay it on the engine block. Ttry starting the engine and watch for spark at the end of the spark plug. Sometimes the spark is hard to see so doing this at night or in a garage will make it easier to see the spark which leads me to another point. Sometimes your sparkplug wires get so old they electrically aren't any good anymore. You'll be able to know that if you start your car at night and you look under the hood and see little sparks jumping from your spark plug wires to ground. This means your spark plug wires need replacing and that could be your problem. Usually the engine will run when this happens but it won't run very good as most of the spark is being shorted out.
So try to isolate where the problem is...Air, Fuel, or Spark and go from there.

GM had problems with the module that controls this. You will likely need to replace the module. I had a friends Tahoe only send cold air to the driver but not heat.

As odd as this sounds, I would take it to "Car Toys" and have them take a look at the stereo wiring.

Interior? Common problem. Cheap online. Like $20

Have you checked the fuses? If all stopped working at the same time, that is likely the problem.

Retained accessory power relay 1 in the left I/P fuse block may be defective, causing power to continue being applied to the radio even after a door is opened to cause shutdown.
