SOURCE: 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.

SOURCE: 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

SOURCE: On my 2003 Chevy Silverado, the A/C compressor

either the fuse,relay,low pressure switch on the low side line near the receiver, your actually low on R-12 freon/refrigerant R134a,or the magnetic coil that holds the clutch in to turn the compressor is bad,you can test all the above problems with a 12 volt tester and a manifold gauge for refrigerant and add R134a legally,but you need a license to purchase R-12 and install it

Heat blowing cold


If your settings are correct and the engine is warm, it will be the thermostat.

One other it could be is a cylinder head Gasket. More than likely its your settings or thermostat

2003 Subaru heat blows cold then hot


I assume you don't mean it just blows cold until the engine warms up. Could be sticking thermostat, air in system, low coolant, vacuum leak affecting flapper door.

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.

I have a 2000 Chevy Venture van and the heat when turned on blows cold. For a while it was still blowing out warm air thru the back vents but now it is all cold. The van wouldn't warm up at all e


needs the water system back flushing out, heater being cold is its blocked up some time a few back flushes and forward flushes with a hose pipe should free up the dirt inside, same with the engine and radiator. there are meany videos on you tube to help you understand how to back flush you engie. but do the radiator and engine and heater separate so the muck does not go back into the engine.

The heater will not blow warm air until you start driving. The fan blows but its cold air. Once you start driving the air turns warm. Why?


There may not be enough coolant in the system. What happends is the heating core is nothing more than a small radiator inside the car. If the fluid is low the heating core is empty. But once you start driving the water pump works harder and fills it up. Another possible cause is a sticking thermostat. If its stuck open the engine cant retain water to heat it up. Thus blowing cold air. Whith the engine cold remove the radiator cap and check your coolant level. If it is full a replacement thermostat may be needed. HTH and dont forget to rate.

Driver's side air blowing warm, won't change


Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.
