    Need 2 things please...

    1st, How do I know if my 94 Deville 4.9 has a heated windshield. I need to know this for which belt to buy. 2nd, Last night I heard a low tone moan coming from under the hood and I could feel it in the steering wheel and I shut the engine off and cranked the car right back up and the sound stopped. "Any ideas" Seemed to be possibly the power steering pump but it wasn't hard to steer and its full of fluid. I am taking a 1700 mile trip in it next week and I would rather not break down. Thanks for any help.

    Not sure on the heated windshield, as for the noise I would assume the PS pump, were you in reverse at the time? My pump has made noise in reverse only, not while in drive yet. IF you do anything at this point I would just drain and refill the ps fluid if its old and that may hep quite it own

    Use a piece of hose as a sthetoscope to locate the source of the noise with engine idling. Be careful.

    The heated windshield has a special button for it, and a heavy duty alternator. You'd know if your car had it, it's a very rare option, since it was so expensive. Also, the windshields aren't made anymore, so if they do crack, it's either find a used one, or a non-heated replacement.

    Thanks to all, I found out I don't have a heated windshield and I have drained the ps fluid and tomorrow I will fill it back up and see if it still moans.

    Did you find the correct procedure online? I believe you have to get all the air out of the system by lifting the wheels and turning the steering wheel. I have detailed instructions somewhere, I need to do this aswell.

    No, I didn't find it online. A friend told me to jack it up though (after I was done) but it still moans a little. I just bought a new pump and am going to replace it if it doesn't get any better.

    Take VIN to parts dept at dealer. They can tell you if car came with heated windshield.

    Air in power steering system. Jack up front end. Turn motor on. Turn steering wheel right to left 5 or 6 times with engine running and wheels in the air. That will get air out of system.

    Good luck.
