Check vacuum line running from left side of fuel injection to the right side by the blower motor it is a small diameter line. if that came apart you will only get air coming out of defroster exits.

I have had this same problem on two astros I have owned. The 1/8 inch diameter hose is broken. Both times it was just above the engine, front and center. The heat from the engine makes this plastic vacuum hose very brittle and it just cracks and fals apart. I was able to mend the broken hose with a larger hose used as a slice. If it is broken off at the firewall then good luck, take the dash apart to get to the other end of the hose. Lousy design in my opinion.

The air conditioning does not blow through front vents but through windshield vents, what is the problem?


This is a common problem on all Astro/Safari vans. The problem is a leak in the vaccum lines that control the vaccum switch responsible for changing air direction from the defrosters, dash vents, floor vents..etc.
Many of the problems that plaque the Astro/Sarfari vans and many other "Mini-Vans" is the build up of excess heat in the engine compartment. It\'s a tight place to put a V6-4.3 Vortec engine and the heat generated bounces back and cooks everything on the engine (coils, modules, sensors, wiring, and of course plastic vaccum hoses). No need to mess with your switches or anything behind the dash -- replace those thin plastic vaccum hoses to operate the vaccum switch (located just below the A/C canisters, to the right of the heater/ac blower housing) and your dash switches will magically send heated or cooled air where you want it.

Heater &air wont work


Resistor , check it out. Conect power to the motor direct , see if it rotates. Hot wire it with a fuse and a swich through the resistor for different speeds. It will be manual not auto unless you want to change the module. Re calibrate the vent doors , and do a diagnostic if you have tha auto modul . Vitally

There is a flap in your heater box that is controled by your vent switch by your heater controls. listen for a vacuum leak. that is common and hopfully the problem. there is vacuum lines that control the vent door that redirects the air to your vents.

Has your dash been messed with recently? if so i would check there first. you should hear a hissing if thats the problem.

Otherwise these also are common for that door flap to break and not switch NE more. thats the only 2 things that i can think of off th wtop of my head to be the problem. this would require the whole dash to come apart if its this problem

The control module is located just behind the ignition coil. Sorta hard to get to but we got it and the van is running great.

i suspect the vents are controlled by vacuum and are not opening due to a vacuum leak.
