Question about 2004 Chevrolet Silverado 1500 Crew Cab

1 Answer

Intermittant hot/cold air from heater

2004 Chevy Silverado with dual zone climate control. Automatic 4.7 liter V8. Truck takes a bit longer than I m used to to heat up and will blow hot air from a ny knob position for awhile, then go to cold air. I dont think its AC, but its cold /cool air. May be a coincidence, but it seems that if its blowing cold, accelaration will bring the heat back up. Always goes to cold air at idle.

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.

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.

Take battery cable off for 5 mins, then put battery cable back on. Insert your key into the ignition turn to on but don't start the vehicle wait 5 seconds turn back off repeat the key on/off three times. This initiates a re calibration of climate control equipment and actuators. It will fix your problem.

My 2004 Chevy Silverado Crew Cab dual Climate control appears to be malfunctioning. The passenger side is blowing hot air with the controls set on AC mode ( 67 Deg ) and the Driver side working...


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

No hot air on driver side. Pasenger side has hot air.


if it has dual zone climate setting it could be stuck in the cool setting. if it is not blowing any air it could be the duct came loose and it is blowing the air inside the dashboard. it will require you to pull the dash apart to inspect what the exact cause is. it could be anything from a bad temp setting switch in the climate control panel to a bad vac line that that switches the air from hot to cold. any other info you could give me may help such as if it is full electronic climate or manual knobs, dual zone, is it blowing any air or just no hot air.

2004 Chevy Silverado AC is blowing warm air on passenger side.


You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator
