#176 of 237 92 Chevy Astro Vacum Heater Controls not working by gpgould Nov 10, 2008 (6:03 am)
I have a 92 Chevy Astro . the heater vent doors are closed in all positions and the blower motor sounds like it is working in the 3rd & high speeds only. But you can not feel any air coming out anywhere. Where do I start and what do I do.

Replying to: dannyboy8793 (Dec 06, 2008 2:04 pm) These vans require that all vaccum lines are intact with no breakdowns/deterioration. Validate all of them first. Check all fuses both under dash and under hood. Then, there are 'blower resistors', usually one near the heater assembly under the hood (my 1996 front B.R. is right in the housing for the air conditioner evaporator. It has a large wiring harness going to it. One of my leads shorted out...Take out the rear seats in the van if you have rear heat, and check the blower resister there also...
#179 of 237 2003 ASTRO VAN BLOWER MOTOR by bassman3112 Dec 10, 2008 (8:25 am)
What is the easiest way to change out the blower motor? It is located way back in the passenger side of the engine compartment. It seems to have a plastic shroud around it. Replies to this message: edcny (Mar 24, 2009 2:56 pm)

Replying to: westal (Dec 23, 2008 9:52 pm) I believe that's it. My rear heat wasn't working, but finally did after I removed it and drained it out, etc. Then, I also swapped out the vaccum tube in front on the diverter...

#183 of 237 1999 astro blower goes on & off by onemanonevan Dec 28, 2008 (1:29 pm)
I've read a lot of post, and never saw this problem. The blower works when it wants to (all speeds). Hit a hard bump and it sometimes comes on. The other day, I released the emerg. brake hard and it came on. Apparently not a vaccum problem. Air is directed to correct vents. Ground connection perhaps???

Replying to: onemanonevan (Dec 28, 2008 1:29 pm) I'd still say its vaccum. I used to slam my hand on the dash and it'd work, then fail...But, do also check your electrical switches with a meter. They could be faulty.
#185 of 237 No Heat At Idle by westal Jan 08, 2009 (9:02 pm)
Recently replaced heater core because it blew out and leaked all over!! Had great heat before change of heater core, but now with new one no heat at idle. Took it into repair shop, they changed out the heater core again, changed out water pump, and still no damn heat at idle. But at high revs awesome heat. Tried to burp system to get air out. But there doesn't seem to be any air in there?!!? Any suggestions on what to do this is getting really frustrating in this -50 weather we have been having in Saskatchewan.
