There is a vacuum line that is operated by your selector switch, it is located under the hood, roughly in the center, up against the fire wall. If the line has leaks, your selector switch will not work and therefore your blower doors will not open and your heat will not be directed to the cabin of your vehicle. Replace the line.

You have to take most of the dash apart to get to the heater switch.there are several screws that hold it in place but the parts on the dash where the gas guage and other guages has to come off as well

Heater/acblower fan doesn't work on high. Other fan speeds work ok. what is the problem? It's a 2003 chevy astro van


Hi, check fuse 12 first. If it is good, you will need to replace the blower resistor. The high speed relay is built into the resistor. The resistor is next to the blower motor and looks like the picture below. There is a connector in the resistor and the 2-wire connector coming out of the resistor attaches to the blower. The blower is usually under the dash above the passenger's feet. You may have to remove a kick panel to see the motor and resistor. Please let us know if you have any questions, and thanks for using FixYa.

Do you have to remove the dash to get to the front heater core on a 2000 Chevy Astro Van?


hello, should be able to get to heater coil on passenger side under dash, you will have to pull a cover thats over the heater coil off, there should be between 5 and 10 screws that hold cover on.

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.
