Make sure it is full of coolant, and the heater valve is functioning, it is locate in your heater hose line somewhere between the core and the engine. If these all check out make sure the damper that control air flow over the heater is working properly. I hope this helps.

Engine won't start, just clicks then eventually starts. 1992 chevy astro


Have entire starting and charging systems inspected and tested. Many components can cause these symptoms, poor cables (corroded), poor connections to battery (corroded), weak battery (old), tired starter. Alternator will not charge the battery properly if connections or cables are in poor shape.
good luck

I changed the thermostat, and it is working properly in my 1999 chevy astro van, But it only produces cold air. All settings only produce air from defrost setting. Thanks Keith

1992 CHEVROLET ASTRO van no heat?fan works find just theres no heat coming out of it.


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

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.

Our 2001 Chevrolet Astro Van heater not working?


Could be a bad heater core, any fluid leaking around it...check under the carpet and padding if you don't see anything under it on the ground. Your coolant may also be low, and it isn't circulating to the heater core, or a vacuum line may be off the hot/cold gate on the heater box, there are a lot of possible causes, but i would check for leaks and fluid level first

2000 chevy astro cargo van. the heat registers on the gage but little comes out and only out defrost. thermostat????


If it is blowing hot air out of the defroster and not out of the heater vents then the door that directs the heat from the defroster isn't working properly it is blocking the heat from going to the heater vents. Also check the cold air door. It sounds like it isn't closing all the way to shut off the cold air and not letting the hot air pass.

Is the engine warm? If no, replace the thermostat. If yes. Is their cold air coming from the heater outlet? If no air look for the fan or heater control .
