I have been posting about my 04 lade but I have a few problems with my 02 Denali that I thought you guys could help with. There is a howl/whine from my front end. A couple of lights out on the window switches and radio controls on the steering wheel. And finally one of my seat heaters does not work. I am most concerned about the front end noise. Sorry for the lengthly list, but you guys have been a great help. Thanks.

The whine is your gears getting ready to go in your front diff, you could trying chaging the front diff fluid, but usually when you get the whine it's too late. It really helps changing the gear fluid every 25k miles to make it last longer

Thanks, I will have that checked out. I know its hard to predict but ball park how much $ are we talking to get fixed? Any ideas on the other problem items? Thanks.

This is just a guess but probably 2k

Your seat heater could be a simple connection problem, or the eliments could be burnt out, same with the window switches, it's a cheap replacement unless they are part of the key fob like the Escalade switches are, my 02' was about 150 to replace the passenger side window switch. Some you can replace bulbs other you have to replace the switch.

Holy differential Batman, that is some serious cash. I will have to do some serious shopping around. Thanks for the help though.
