Little thing are happening

I have a 98 Pontiac Transport/Montana. When I turn the steering wheel left to right I hear a squeaking inside the car--What is that? Also, I have radio controls on the steering wheel--Lost the lights for those---How do I fix that? And, My climate contols says "ice" when it is 70 degrees---How can I fix that? And my fog light burned out-Do I need a new light or just a bulb? And where can I find the two new grill pieces?---mine broke off and are rattling. Thanks, Dana

And, My climate contols says "ice" when it is 70 degrees---How can I fix that?Replace your outside temp sensor. It's a small grey/black sensor just in front of the radiator to the left. It's like $10 or $15 to replace it.

And my fog light burned out-Do I need a new light or just a bulb?Most fog lights I've worked with have been replaced as a whole unit, but I can't say for sure for the Montana.

And where can I find the two new grill pieces?---mine broke off and are rattling.Junk yard or dealership. I beleive they come as a complete assembly already fastened on to the piece that attaches to the hood. I don't think you can find the individual grills not already fastened.

Also, I have radio controls on the steering wheel--Lost the lights for those---How do I fix that?
Did the lights go out at the same time? My manual says there is a 2 amp fuse that feeds those.

Is that on the OVERHEAD display? If so, what CDRU said would be my guess too. Or you could have a loose connection to it. Here is a link that shows where it is on my 2001 Venture.

My manual says it is a single assembly (not just a bulb).

Take Care,
