The 4 wheel drive switch is going bad in my truck and I really never use the switch. Has there been a recall, will Chevy take care of this problem? also the pulley or compressor for the heating and air makes a noise when I use the air system in my truck. I own a 1999 Chevy Silverado Z71, and I feel Chevy should help me out and fix these problems. Also the fog lights have never worked on the truck and daniels would not fix them for me.

Vibration in drivetrain at speeds less than 45mph. Engine only runs 1,000-1,100 RPM's at speeds less than 45mph. Transmission shifts into 3rd at approx. 20mph and 4th at approx. 30mph. Engine feels like it is struggling at speeds less than 50mph. Two different dealerships stated there was a problem, but said that everything was electronic and nothing could be adjusted. A/C is not cooling sufficiently. It only cools on full cool with re-circulation and fan on high. Even then, air coming directly from center vent does not get below 48 degrees. I tested two other vehicles and both blew 40 and 42 degrees from center vent. Two different dealerships admitted there was a problem, but stated there was no fix. Driver-side outside mirror vibrates. Dealer replaced twice and both manufacurer and dealer refuse to replace again. Weather stripping along ouside bottom of both driver and passenger windows is defective. Dealer and manufacturer both refused to correct problem because other stock units look the same.
