#248 of 629 1999 Chevy Astro Van Heater/AC Controller
Aug 11, 2005 (4:42 pm)
I have a deteriorating problem on my van. When I bought it used, the blower/fan only worked on 4 and not on 1/2/3. Not a big deal.
Recently however, it has - intermittently - stopped working on 4 as well. There is no rhyme or reason as to when it works or not.....you can have 3 or 4 days of it working without any problems on 4 and then a week of nothing.
A month or so however, things continued to go downhill. It suddenly decided to blow onto the windshield only, and not on the face or floor vents. I rigged something up to redirect the a/c from the windshield via a pvc pipe onto my face to try and keep cool in the humidity. Unfortunately, this isn't very practical and not making me look a cool dude to friends and family!
I purchased a new contoller unit (about 8" long with the three knobs for the blower, heat/ac control and the locator button (floor, wwindshield/face). I was dismayed to find that this didn't solve the problem at all - everything remained as it was before and I therefore returned the new part.
I'm hoping therefore that someone can shed some light on what the problem may be. I'm being a cheapskate by not going to Chevy as the van has done 200,000 miles and i don't want to throw a ton of money into something that may well be on its's last legs anyway. I'm hoping that one inexpensive fix will sort out both issues.
Any comments or suggestions whatsoever would be HUGELY appreciated.

The "buck and misfire" symptom sounds more like fuel injectors to me. I'm not a mechanic, but have had 4 vehicles that all did that and all 4 were fuel injectors. I would recommend checking them and/or cleaning them. Also, check all the other firing compontents...plugs, wires, etc.

Refer to the lst few lines of post 246 on how to fix the problem on the a/c not blowing out the vents. Very simple fix involving an 1/8" dia plastic vacuum line. I am not sure on fixing the blower motor switch problem, it has not happen yet to my van. I would have probably done the same and purchased a new control unit. If it is an intermittant problem that it usually is caused by a loose wire or connection.

The low pressure port is the only one the guage that you get when you buy the service kit will fit. I have a 96 and it's in the passenger side engine compartment next to the exhaust manifold. The end of the guage that hooks to this port should only fit one fitting. That's the low side port.
#255 of 629 98 Venture Interior Electrical System Shutdown!!!
Aug 12, 2005 (5:52 pm)
I have 1998 Venture LS and I be driving along on a hot day with the air conditioner on and then for no reason the electrical system inside the cabin shuts down. The system shuts down the A/C system, blower fans, radio, door locks and power windows. Everything is quiet. What stays on is the interior lights, signal lights and head lights??? Has anyone ever had this happen to them? If so did you find the cause and what was the fix? This is driving me nuts???
#257 of 629 Blower Motor and Pwr Window Problems 99 Astro
Aug 13, 2005 (5:07 pm)
Blower motor in '99 chevy astro van making lots of noise.
Sounds like a bushing is without grease. Do these motors have bearings or bushings? Sounds like a leaf is caught inside housing but has been making noise on & off for 4 weeks now. Van has 199k miles.
Also drivers power window only goes up 2" at a time. Needs to rest for 10 minutes before it goes up another 2". Similar problem going down.
latest problem is that ac compressor clutch sticks and doesn't engage. Makes a
rattle/ buzzing noise for 5 seconds then engages.
