I would suspect the ignition switch in the column is the issue. NOT where you place the key but the electronic part behind the key. Hope this helps
SOURCE: Grinding noise on 2002 Olds Bravada
Try making tight turns to the right and then to the left. see if the grinding noise comes and goes. It could be your C/V joint and they need to be replaced. The noise will only come when your making the tight turns, you don't have to go fast. Walking speed will do and you can hear it with the window open or someone walking beside the Bravada. Good luck and keep me posted. Be glad to help.

Either have broken wires leading to the heated seat and the power seat controls, or the heated seat element is burnt out (but not likely).
Check for blown fuses for the system, but if one side or the other is not working, it's more likely a wire broke somewhere, in this case, on the passenger side.

If the blower motor doesn't not turn on than its very likley that the blower resistor or the blower itself is bad. This will help figure out which one of the two it is.

SOURCE: got a p0304 code come
P0304 Code - Cylinder #4 Misfire Detected
A P0304 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #4.
Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present
Causes: A code P0304 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer
Possible Solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Hope helps.
