SOURCE: Climate contol does not light up.

Unfortunately the bulbs that light up your climate control are not replaceable and in order to get it to light back up again you need to replace the climate control unit.

SOURCE: Impala has dual climate control. AC blows cold on

with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!

SOURCE: 2004 chevy tahoe, dual climate control, blowing different temps

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

this problem is caused in almost all cases by a failed actuator that moves the door insiode the heating/ac duct to change the outlet temperature, it is called the Air Temperature Control Blend Door actuator.

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.

you may need to have the controller re-calibrated. There is a TSB at the GM dealerships on this. What is happening is the the blend door control for the pass side has OVER-travelled and is stuck in a default position. You can try to pull the Blue fuse under your hood for the HVAC, for about 5-10 minutes and put it back in. (with the engine off) Then restart the truck and turn the Climate control back on, and push and hold the Auto button for 4-5 seconds

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.
