If you have no lights and the engine will not crank, the problem could be a bad connection at the battery or starter solenoid, or one of the ground cables.You would need to take a meter or test light and check for power at the battery and back to the key switch. Could also be a burned fuseable link from the solenoid to the fuse box.

PATS System?Check for B codes with a professional scan tool

should be connected to ign fuse and also one behind the radio itself

If neitrher the driver's door master switch nor the passenger door window switch wont operate the window, and the lock-out button is not on, then likely the passenger door inner panel has to come off to investigate. But first, check the wiring going into the passenger door for a broken wire. Also check the wiring coming out of the driver's door. If you see nothing wrong, pull off the passenger door panel and check for any wires loose from the window switch down to the motor. You can hotwire the window motor with a spare battery set beside the door there, to verify the motor is bad. If it is bad, you have to remove the glass, then remove the window regulator with motor attached, in order to replace the motor.

Hi SM, I believe I would carry out a diagnostic scan, looking in particular for a defect with a speed sensor, ABS sensor or traction control sensor, Which incidentally all use the same sensor from each wheel. These same sensors also control the gearbox changes and operation. Regards John

We don't have the wiring diagrams for this but if you really are that interested you can buy the book here that shows the whole electrical system.

i would check your power steering fluid and look at your hydro booster for any leaks your power steering is what powers the brake system on your car because it does not use vacuum an when my abs light was on an trac was stuck off it was just the fuse so i would check that hope that helped you any

The main radio fuse is in the fuse panel inside the vehicle in the fuse panel to the left of the steering wheel down by the brake pedal. Below is a fuse layout diagram of that panel. I marked the fuse you are wanting to check. This should be in your owners manual if you have one. If you do not have an owners manual and would like a copy of it, feel free to email me directly at [email protected] with your make, model and year and I will be happy to email you a copy of it. Hope this helps....

pull out 1 fuse at a time and look at the wire trace inside if it looks broken or black, replace it. if it looks good. put it back in and keep trying

test for voltage at window motor plug. if there is voltage replace window motor. not a very fun job.

Did you check to see if the radiator fan is working ?

Do you know if the compressor stops working when you are getting hot air ? The computer will turn off the compressor when you are at wide open throttle. Could be the throttle position sensor or a vac leak among other things.

It is under a panel in the front of the trunk behind the rear seat back

Check it but chances are you fried the radio. The fuse location is in the owner's manual if you don't have on you can access a pdf copy HERE
