#1459 of 1497 Help disabled student choose.. by tempo9 Aug 05, 2008 (4:13 pm)
Hello:     My disabled son is choosing between a 1998 Buick LeSabre with 83,000 miles on it in pretty good condition; we are getting it inspected tomorrow and will get a CarFax report as well. car is being sold by "Louiie's Cars" (not real name)... runs and rides well. Dealer wants 4995. The other car is a garage kept 2000 Park Avenue loaded with 107k miles sold by an elderly gent for 6,000. Car is in pristine condition; we haven't driven it yet.  Question: If the Park Ave is in good running/mechanical condition which would be the wisest choice? He has very little money and doesn't know how to fix cars. HELP!   Thank you Tempo9 (devoted to my Toyota Highlander Replies to this message: mariannesam (Aug 07, 2008 9:06 am)

Replying to: vincem1948 (Jul 25, 2008 10:18 am) Should be under warranty as it sounds like an emissions issue and these usually have longer warranties (check your owners manual or call a GM dealer). If its under warranty, take it to a Buick dealer (if not close, any GM one should handle it).   Also, once a problem is fixed and not cleared by an external "reader" system, it may take serveral on/off driving cycles for the code/light to clear.

Replying to: julie23 (Aug 05, 2008 11:48 am) When its blowing hot, you should see that the AC compressor is not turning.   I think its the high pressure AC sensor.   When its not working, try taping/hitting the switch (ask some mechanic to show you where it is, should be on the AC high pressure line near the compressor). If the compressor comes on, then it the switch.   The switch is about $70 from dealer and should not be that hard to install. Should not have to drain the freon to change switch.   This switch is a problem with many GM cars.

Replying to: mariannesam (Aug 07, 2008 9:02 am) I've got the extended warranty, but if it is not covered under the warranty, I'd be looking at an expensive diagnostic testing. Received a tip on another forum and it seems to have fixed the problem. I was told to check the filler neck lip where it touches the gas cap and clean any build-up of rust or dirt off it. Found quite a build-up along the upper portion of the filler neck. Took a green scrubbing pad and with a little elbow grease and some 409, I was able to clean it back down to the metal. Put the gas cap back on and started the car and let it run. After about 5 minutes the error code went away and the Service Engine Soon light went off and has not returned. I'm keeping my fingers crossed. (It seems that Firestone uses a different kind of cap that expands out inside the neck, by-passing the filler neck lip.)

#1466 of 1497 '90 Buick LeSabre stalls when lukewarm. by ubisum Sep 24, 2008 (11:36 am)
My 1990 Buick LeSabre, which I have cared for very carefully for lo these many years and which has consequently been running well, barring the occasional but minor glitch, has not been feeling well of late. About 15 to 20 minutes after I start it up from the cold-engine state, it stalls, sometimes hesitating before doing so, or sometimes just cutting out completely. Then, sometimes but not always, after I restart it, it will re-stall within 5 to 10 minutes. After that, it runs fine, at least until the next morning when I again start it up from its cold-engine state. Some days, however, it doesn’t stall at all. The EGR valve was replaced and the problem persisted. The air-intake system was fixed, at least according to my mechanic, and the problem persists. I would like to hear from a Columbo of automotive mechanics, someone who can help me avoid having to blow more money on ineffective solutions, please.

Replying to: icnfixxit1 (Sep 09, 2008 8:14 am) If the horn stays on continuously, then it is likely an issue with the switch that is in the steering wheel above the airbag unit. This is a major design blunder on GM's part. The switch was VERY poorly designed and expands upon getting hot. Usually this happens when the car is sitting out in the sun, but can happen anytime.   You have a couple of options you can try: 1) You can take the air bag unit off of the steering when and disable one of the horn switches. Test to see which one is causing the problems with a volt meter. To take the air bag unit off you'll have to disconnect the negative battery terminal. Then pull the airbag fuses out of the fuse panel below the driver's side dash. Pull the kick panel off of the drivers side and disconnect the yellow connector (to completely disable the airbag). Use a torx bix to loosen the screws on the back side of the steering wheel. This will release the air bag unit. Once you pull this off, you'll see another yellow connector and and a black connector for you radio controls. There will also be a spring type clip that goes into one of the holes and a longer plastic tube with a spring attached that goes into another hole. If you put a volt meter on these two connections you can test the switches. Once you've found the switch that has a problem just leave that one disconnected. There are two small black plugs. Usually, one of the switches is more sensitive than the other and you can just disable that switch. The horn will only work when you push the steering wheel in the specific location of the switch you did not disable. 2) You can buy a new airbag unit which will obviously have a new horn switch that should not have problems for the next 5 years.

Replying to: ubisum (Sep 24, 2008 11:36 am) It sounds like it may be a problem I had a while back with my 88 Chevy van. There is a coil that comes off the crank shaft that sends a signal to the CPU and tells it to send spark when the crank shaft is spinning. The coil on my van went bad, but it was ok while the engine was cold. After 10-20 minutes when the engine was hot the engine would just quit. It would only restart after sitting for an hour or so. I replaced the coil and it ran perfectly again. Check to see if this is a possibility. If your 90 lesabre has a similar coil, then this could definitely be your problem.
