#2 of 249 mysterious electrical issue by regalmama Jun 14, 2005 (6:23 pm)
My 1997 Regal suddenly had no A/C fan, cooling fan or cruise control working. After 15 minutes or so, everything came back on. Now it happens every couple of days, lasting from 15 minutes to 24 hours. When they're not working, turning the fan knob on cause the headlights to go off completely even though the fan won't come on. I've had the battery and alternator checked and they're OK. Anyone have any suggestions?

Replying to: regalmama (Jun 14, 2005 6:23 pm) Without knowing how the car is wired, my first thing to my mind is a ground problem. With an older LeSabre there are a couple of ground coupling points; one is by the left driver foot in the kick panel, the other is next to the driver seat between it and the door sill. It's a box long and thin under the carpet, just where my fingertips would touch while seated in the driver seat.   That car had loss of air conditioning control (reverted to compresser engaged and defrost sometimes) and power door locks quit for a few minutes or hours...   Moisture affected the grounding connections under the carpet from snow, rain, getting in there and keeping it moist for long periods.

Replying to: regalmama (Jun 14, 2005 6:23 pm) I have a 98 Regal and am experiencing the exact same problem. I have found that I can leave the fan switch on high and the fan and lights work fine. Still no cruise though. I was wondering if you have found the culprit to this problem. Thanks Replies to this message: dccmorrell (Aug 04, 2007 10:36 am)

Replying to: tkh (Dec 01, 2005 4:09 pm) There is indeed a "Low Tire" reset switch. It is located with the fuses on the passenger end panel of the dash board.   With the front passenger door open: 1. Pull the fuse access panel off the end of the dash with your finger (might need a good yank). 2. Locate the red button marked "Reset". 3. Turn the ignition switch to the "On" setting, but do not start the engine. Note how the "Low Tire" indicator comes on. 4. While watching the dash indicator reach back and press and hold the reset switch. The "Low Tire" light will flash a few times, then go off after just a few seconds. 5. Release the switch when the light goes out. 6. Replace fuse access panel and close the passenger door.   It might be worth remembering this procedure as you will need to repeat it after any of your tires are removed, such as when rotating tires or doing brake work.

Replying to: tkh (Dec 03, 2005 5:04 am) You're so welcome! By the way, since you don't have a owner's manual, the thought occurred to me that you may not be aware of the passenger cabin air filter. Some of us replace it once a year. The replacement is usually filthy. Anyway, if you decide to tackle the project, there are instructions in post #1281 on this board. I recently found a good price for replacement elements at speedycarparts.com, but you might have better luck shopping around.   Also, I highly recommend you inspect the condition of the engine coolant. Perhaps you have heard some of the horror stories going around about Dex-Cool (nick-named "Death-Cool"). It is touted to be good for 5 years or 150,000 miles, but many who trusted that statement have found sludge in their radiators and having to replace head gaskets at around $850. My suggestion would be to check the level in the overflow tank monthly to avoid letting air get into the cooling system, and to have the system flushed after 3 years, not five.   All the best, Ken.
