Three problems related to wiper have been reported for the 2008 Chevrolet Avalanche. The most recently reported issues are listed below.
My 2008 Avalanche ltz was parked on the street during a snow storm, after I started it I turned the wiper switch to delay to clear the small amount of snow on the windshield. The wipers moved form park to approximately 1/3 of full travel and stopped. I cleared the windshield with a brush and drove home (1 mile) with some difficulty. I started to troubleshoot the problem, and came to what I thought was a solution, multi-function switch was bad. Replaced switch, sill no wiper movement. Checked the plug at the motor for power (again), power at the plugs hot terminal was 11. 8v, turned switch to on (slow speed) and no power to any other pin, now I am stumped. Guess I have to call the dealer.
The contact owns a 2008 Chevrolet Avalanche. While driving approximately 20 mph during rainy weather, the rain sensitive wipers responded at a slow rate. The windshield had a lot of water on it because of the slow response of the wipers; the wipers did not function with snow. The vehicle was taken to an authorized dealer where the contact was told that there was nothing wrong. The vehicle had not been repaired. The failure mileage was approximately 1,500 and the current mileage was approximately 30,000.
I have had 5 Avalanches 3 07s 2 08s all have dash cracking issues the breaking dashes crack cause glare in drivers eyes noises that can take focus off the road every one I've owned it's happened gm used a proprolyene dash that gets brittle when introduced to heat. This is known by gm as a defect but u guys have not enforced them to fix it's a extremely expensive fix labor is high and I'm 5 for 5 on cracking dashes. 3 have cracked so bad that when the sun hit them they throw glare toward my eyes. It needs to be addressed this is crappy. Just like gm and the crappy Cadillac srx headlights they know it's a defect then fix it.
