i regret to inform you this, but it sounds like your timing belt might have slipped or broken, which can be a costly repair. the best advice i can give you is to tow it to a trusted shop, that is reasonably priced. hope this helps, and goodluck

under the radio.

Freeze plugs are in the engine block. You may not be able to see them very easily because of the intake and exhaust manifolds. There is usually 3 or 4 on each side at about the "center line" and also some on the back of the block where the transmission attaches. They will be round and pressed into recesses.

check connection in wireing back by light before waer they t off

Have you tuned up the car's engine with new spark plugs, wires, and air filter in the last 30,000 mi?

this is a non-interference motor. Most likely it will not be damaged, replace belt and test by rotating the motor w/breaker bar!! Or you may do a compression test.

yes, a fuse and a relay usually under the hood in a black box.

You should just need a extention to get at the plugs and a plug wire puller and you should be good no need to disacemble

Hi,

The sunroof(you suppose) doesn't work manually,its controlled automatically by the button built for it which controls the motor.

However,if it doesn't work automatically,it means the sunroof motor is bad and needs a replacement,perhaps you should check the fuse first before replacing the motor.

Take care
