#2 of 12 Chevy Astro Rear Fan by tom120 Mar 16, 2007 (12:56 pm)
I have a 99 Astro. The rear fan made a loud noise while running then eventually stopped running. Is there a way I can replace the motor or is it something else?
#3 of 12 1995 Astro Gladiator rear Heat? by punchbug Nov 07, 2007 (8:31 pm)
I just recently purcased this 95 gadiator cold ac front & rear, the rear ac quit blowing cold untill I found this vaccum line unhooked, Ok the problem I got and can't figure out. Is my rear heat dosen't work, I have ac and then just the fan,, I feel the hoses at the box getting hot, thinking just one of them. Just not flowing through. Is the a acuator(syleniod) cotroling the switch over in that rear box?? I'm seeing just the fan wires,, don't want to gut the whole wall out untill I know,lol Thankx for any helpful info..
#4 of 12 2000 Chevy Astro Van...No HEAT blowing in!!! by indhelp Jan 26, 2008 (12:00 am)
I just purchased a used Chevy Astro two weeks ago. When I took it for a test drive, everything seemed to be working fine. A couple of day's ago, it didn't seem like I was getting enough heat. It would blow heat a little and then one I didn't hear the fan running. What I do hear though, is a humming sound. Can someone please tell me if it's the thermostat, or hoses, or what it could be. Oh, and the a/c blower in the back works. Please help!! Thanks.

We have a 99 safari. The blower motor resistor is bad (the blower doesn't turn off even with the key out of the ignition). The old resistor had a part number on it from the factory. The part number has changed. We got the new part from the dealer. But they have "upgraded" the part so it does not look like the same thing. The mechanics at the dealer insisted that it would work even though it is shaped differently. The old one had a computer like plastic card sticking out of it about an inch. The new one is only half the width but sticks out about 2 inches and is 1/2 inch thick. The Chevy mechanics insist that it will fit. My question is "do you have to do some sort of modification to the vehicle in order to make it fit?" I tried to put the part in, but it wasn't even close. What do the Chevy mechanics know that I don't know? Replies to this message: lloydroy (Jul 02, 2009 5:48 pm)

Replying to: kortic (Apr 02, 2008 12:29 pm) Have the exact same problem with my 1999 Astro. Fan runs on high only and runs on high even with key out. What was the outcome of your same problem and how much did the blower motor resistor cost you? Thanks for your help
#11 of 12 Climate Control Problem by lanceosh Nov 19, 2009 (3:07 pm)
I had a problem getting the Heater A/C working properly in my 1998 Safari. Took it back to the dealer who put in a new control (The one with 3 holes attached) now I get all kinds of air to the various areas and I can get the A/C to work BUT absolutely nothing beyond a luke warm(cold) air when the heater is turned on. Living in Canada we need a properly running heater in our vans! Now the dealer is suggesting the thermostat may be stuck and wants to replace it (of course at my cost) Could this also be a vacuum problem?
