SOURCE: 2002 Astro van ventilation fan problems.

The problem is a 1/8 diameter hose that runs from the front of the engine over the top and connects at the rear of engine on the drivers side. It is a vacuum hose #GM15967970 It cost about $6.22 at your GM dealer. Hope this helps Bill. My E-Mail is Uflyups@aol.com

SOURCE: 1998 Astro Van Heater AC Blower only works on medium & Low

Yes, in high it bypasses the resistor and uses a high blower relay. But I think on 1998 Astro the High relay and the resistor are built together. It should be mounted in the blower box real close to the blower motor.

Yes it could but also check under the hood because it is a very common problem for a vaccumm line to come unhooked causing this problem. Hope this helps, Allen, swiftautorepairs.com

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.

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.

I have a 93 chevy astro van and the blower fan keeps blowing fuses. the fan checks out good, can't locate the relay which I think may be bad. as I can unplug fan and still blows fusew.


The relay is not your problem or it would blow wheather or not the heater motor was plugged in or not if it was shorted,you need a new heater motor.

No heat


As for the fan your blower resistor is in need of replacement.
To address the heat problem I'll need to know a couple of things
1. Does your vans temp gauge read in the normal range or is it running low(after you've driven it for at least 10 min
2. Is the out side temp really cold?
