Maybe I shouldnt be surprised since 2 out the 5 blower speeds stopped and half of the lights in the intrument cluster went out and NOW my mirror with outside temp and direction stopped working. Gotta love that GREAT GM FEELING...........all this with 20,000 miles on an 04 silverado. Man, I can't wait to see what the next 20,000 have in store for me........or should I say for the first sucker I dump this truck on. Anyone else have their electic mirrors stop working. WOW!
