2003 chevy 1500 ss only blows cold air no heat


Dual climate control on these is not a manual valve adjuster. It is done electronicly with a electric motor on a valve instead of ran by a maual cable. Find this and check the plug for a 12 volt signal. If you are getting a signal replace the valve, if not it could be a blown fuse, cut wire, or a bad climate contol switch.

My 2004 Chevy only blows warm air on the passenger side my driver side is always cold. It has a dual air systems, but my A/C works great on both sides. What can i do to fix this problem ?


i am an owner also same vehicle there is a baffler in the center of the console next to the front window it you can find it cause there is a little hole you cn see this controls the air distribution to the driver side . i tried getting to it twice it is difficult to remove all that. Was close but ran out of time and gave up was quoted over $300
to repair if i removed the steering wheel it might have been easier to solve . good luck

Intermittant hot/cold air from heater


Had the same problem with my Mazda6 awhile back. Took it to the dealer and they found the radiator wasn't holding pressure. They replaced the whole radiator under warranty (WHEW!). Not sure how to check for that kind of thing, but it's a start.
