Your Bonneville might not be running as hot as you think. I own a 93 SSEI that at full operating temp looks like it's running at about 225, the needle being just above the mark between 200 & 240. At that point, the secondary fan turns on and it cools off to what looks like 210, then the cycle begins again. If you connect a scanner to the diagnostic port, while the needle shows 225 the temp is actually only 208 which is about what they're supposed to run at. I would say the true temp from the sending unit is not being correctly reflected on your guage.
Also, to the guy that talked about his car not having vent circulation, I agree with the earlier response you received about the evaporator being clogged. I replaced mine for the very same reason and vent flow was vastly improved.
I'm a longtime Pontiac guy. Currently own a 93 SSEI, 95 SSE and an 02 SLE, so while not being a certified mechanic I'm pretty familiar with Bonneville problems. Now If I can only resolve the ABS & Traction Control lights that stay on in my 93 SSEI that spits out multiple codes, I'd be happy. I've replaced both rear wheel sensors to no avail. Would like to know if the pump or computer would be next logical step. Errors point to both.

alcan! The ABS/Traction Control lights stay on solid and the codes I get are:
033 R/R Missing 037 L/R Missing
045 Inlet Valve 061 Pump Motor Run Fault
It was suggested I replace both rear wheel sensors first, which I did. No change, still get the lights as soon as the car is started. This is on my 93 SSEI.
#1728 of 2268 climate control
Dec 28, 2005 (9:16 pm)
I have read a lot of post about this, but not sure if it is the same as my problem. My climate control display on my 96 bonneville flashes once and a while. When this happens my heat will start to blow out cold air. The only solution i have found is to manually go back and forth with the temp guage from 60degrees to 90degrees, and usually after about 5 minutes of doing this, it will finally kick back on. Or sometimes if it does this, i will simply turn the car off, then back on and sometimes the heat will kick back on. Also on a long trip, i wont even have the heat on, but my cabin of the car gets super hot, almost to the point of unbearable. Heat seems to be comin out of the floor vents, but not in a fast manner. A few weeks ago my heat was working perfect, then i had to replace my battery, and once i put a new one in, that is when the heat startin acting up again. Anyone have any ideas. Could a ground wire be loose? I heard some talk about vacumn lines, does that have anything to do with it? if so where are these located? Can i just reach in and examine them. Any ideas would help greatly since i am a poor college kid who is really cold this winter!! Thanks

on my 96 bonny, whenever i hit the defrost button, the A/C light always comes on. Is this normal? I didnt think that the AC should come on when i am lookin to defrost. Anyone want to share what happens when you turn on your deforst. Thanks for the input!

On any GM car I've ever had, the A/C Compressor engages on defrost cycle to dehumidify the environment. What you're seeing is normal.

While driving on freeway, car gas pedal did not respond. I coasted off freeway. When restarted, car would not go in reverse, but only forward. It makes a clanging noise when going in drive. Is tranny shot or might no reverse be due to something else? Thank you for the help.

You may want to check your tranny fluid first. the proper procedure is in the owners manual. When the fluid is low it will cause that to happen.
#1733 of 2268 95 Bonnie boost guage
Jan 04, 2006 (5:55 pm)
I have a 95 ssei and this forum has provided a lot of help. The boost guage at idle reads in the negative. the owners manual reads as if it should read 0 at idle. is this normal or did I miss read the manual?
