SOURCE: Intermittant hot/cold air from heater

SOURCE: ac blowing hot air
the blend door actuator located on the air box (right hand side under dash) is prob. inop. worst case senerio the blend door its self is broken. I have replaced the actuator more than anything.
SOURCE: chevy astro van heater blowes only cold air
the problem is probably the heater core, it can become clogged with dribris. this stops heat from the engine getting to it and then no heat.

YOUR VEHICLE HAS DETECTED A FAULT IN THE AIRBAG CIRCUIT IT WILL HAVE TO HAVE CODE RETRIEVAL DONE TO DETERMINE WHAT CAUSE LIGHT TO STAY ON,I URGE YOU TO DO THIS SOON AS WHEN AN AIRBAG SYSTEM HAS GIVEN A FAULT CODE AND TURNED ON THE LIGHT THE SYSTEM IS DIABLED AND WILL NOT PROVIDE PROTECTION IN ACCIDENT
