2004 Silverado Ac Kicks Off On Left Side

[kc5gxc]

Friend has 2004 Silverado. AC has control for each side of cab. The left

side and the speedometer will quit working at same time and hot air comes

out of left side vents. It's an 8 cyl, ext. cab. 42 k miles and 2wd.

Warrantee is out but still on for this problem as it has been ongoing....he

has had it back to dealer 5 times with no fix. This is an intermittant

problem. Taking it back in on Monday for the 6 time. Once it does this, it

will not resume normal operation until the truck is shut down for a few

minutes....anyone know of a fix so he can tell the dealership what to

do????????(he is a lifetime Chevy man, but fed up to put it litely)

Thanks, Pete

the 2 problems are not related... has he had the cluster replaced for the speedometer? if not, replace it... those clusters are the biggest peices of junk ever made, i replace 2-3 clusters a week for different problems... the problem with the a/c is most likely the air temp actuator for the driver side, it isnt the easiest job to replace, you have to pull the dash back to get to it, and it is on top of the hvac case... do you know what the dealer has done so far?
