I have been having the same exact issue for the past couple of weeks. I have '98 Venture. I don't want to add to the confusion, but it seems that if I have the rear AC running, all blower seem to work better. I have also noticed that it I change the blower to blow on feet and then change it back to face, it seem to work better. I don't know what that means, but thought it might help.
I had taken the Van to the dealership for a diagnose. They told me that Discharge Suction Hose was leaking an needed to be replaced. I find it really hard to believe becasue if it was due to a refrigerant leak then it would cause all vents to blow warm air. I also had the compressor replaced and systems recharged a couple of months ago. Warraty covered it. I am so happy that I bought extended warrranty on this Van.
Anyway, I will continue to research on this and if I find something, I would be happy to let you guys know. I hope you two will do the same for me.
I found that there was a clip holding the turn signal housing in place, the clip was jammed. I had to get at it from the wheel well & hammer it out!! Hope this helps other Venture owners!
Thanks again for your responses.
Thanks in advance.
See post #220 :
Your problem with your blower is more than likely the control board for the blower. I have a 98 venture with the same problem and replaced the board which is mounted on the passenger side way up toward the floorboard. The original board had small "resistors" mounted on it that burned up. The replacement board was made much heavier. I expect that this common failure caused G.M. to make a better board to do the job. I paid roughly $30.00 for the board at the dealer.
Is this a common issue? Is it an issue I can resolve myself or should I take it to the dealer?? Any advice would be great...thanks
Tonight (wife said started a week ago), hazard light indicator in dash group lights up steady when brakes applied. Noticed that there were NO rear lights at all with the exception of the third (overhead) brake light. No tail lights, no turn signals, no brake lights - no nada. Looked through manual, no help. Got home, pulled into garage, and WALA - everything works normally - again PFM!!
Any and all help would be greatly appreciated. Thanks, Doug.

Then the right front window wouldn't go down and the front right blinker was blinking fast.
Next (this morning) it wouldn't start (seemed like a really dead battery). We jumped it and it started. But, when we turned it off (even after driving around the block a few times), it wouldn't start ... dead as a doornail. I replaced the bulb, still dead as a doornail. I inspected the battery and the positive post was corroded. I touched it and it literally broke apart with the post still in the battery!
So, I pulled everything apart and took out the battery. I tried to get the post out, but that caused the battery to start leaking acid.
Went to Sears, got a new top-of-the-line battery.
Put everything back together ... all we get is "service engine soon". All else is dead. No lights, no radio, no AC, nothing.
I checked all the fuses, one at a time with a multimeter ... they all seem good.
Any ideas? Is there an electrical system reset somewhere to get the computer back online, etc.?
Help please ... we need this van!
Can I possibly fix this myself?
I hope so... please anyone with any ideas... Thank you.
Hope this helps.
Then this week, it started making this noise, like a whining when I went over 35 mph. Then, my automatic rolled backwards a bit in drive on a hill...hit me then it must be the transmission...Had hubby get in and try it...he said it has no 3rd or 4th gear anymore. Called for service...still under warranty, so we'll see. Anyone else had any similar problems?
I have a 95 Astro that behaves similarly. Sometimes, when the engine is hot, it won't restart after turning off ignition (eg come out of variety store - no re-start). However, 1-2 hours later it starts and runs fine... Very frustrating... Only happens occasionally - about once a week. How did you make out? Did you determine what was causing your problem? Was it the fuel pump as someone suggested?
had the egr replaced wp replaced tune up all four ox sensors and it still acts the same. the dealer said he didn't know what to do. i seem to think the trans is starting in 3rd or 4th gear . took the motor cover off the motor seems to torque to the right when engine starts idling right the motor drops to the left maybe torque conv lockup also had new injectors also catilic converter . any help?
Oh well, figured I would share my pain.
engine on both is 4.3w transmission model e40d to 700r4
