#736 of 1085 Re: Oldsmobile Intrigue Electrical [kiawah] by angelvaugn Mar 11, 2007 (9:38 am)
Replying to: kiawah (Feb 13, 2007 4:43 pm) Thanks Kiawah. I do not drive this car much due to having a company car but I took it out on the freeway yesterday and found out that I can not disengage the cruise control by hitting the brakes anymore. Do you still think it may be a fuse of some sort? When it gets warm in a month or two, I plan to start trying to see if I can find the problem. Thoughts anyone?

Replying to: angelvaugn (Mar 11, 2007 9:38 am) My 94 Ranger pickup had one switch on the brake pedal, which was used both for brake lights and signaled the 'computer' to dis-engage the cruise. I replaced this brake switch 3 times in about 8 years and 40,000 miles on this truck.   And, when the switch went out, it would not disengage the cruise.   Get in the vehicle, have someone watch the brake lights and push on the brake pedal. If you don't have brake lights, the switch is probably bad.   On one of the failures, a Sheriff followed me home and just told me about not having brake lights. No ticket, just told me.

Replying to: matuska (Mar 13, 2007 5:23 pm) The problem went away.   No Explaination except it must have been corrosion in the connection.

Replying to: kirstie_h (Nov 05, 2001 2:32 pm) One thing to never forget to do is check all of your high amperage fuses for corrosion in any wierd intermittant electrical problem. At 40 amps it would take less than 1/8th of an ohm change to make a 2 volt drop, which on modern cars with all of the communication lines going it wouldnt take a large drop to mess up the system.
#742 of 1085 Oldsmobile Alero with Strange "Service Soon" Problem by missguineapig Apr 02, 2007 (7:46 pm)
My 2002 Alero, which has only 29,000 miles, recently started doing this strange thing where I'll start it and nothing lights up - not the little green light for the AC, the odometer, or anything else! Sometimes it lasts a few moments but sometimes it doesn't happen at all. A few times the "service" warning has come on, but not always. If I restart my car, the light usually goes away. Other than this, my car hasn't really had any problems. What could possibly be causing this sporadic malfunction in my Alero? Has it happened to anyone else? Thank you for your help!!!

Replying to: missguineapig (Apr 02, 2007 7:46 pm) Since the 'Service Soon' light is turning on, a code is being set and remains in the computer even when you restart and the light does not come on.   Therefore, have the 'codes pulled' and see what the computer is 'seeing' as an invalid value from some sensor, etc.   After market parts sales places (Autozone, etc) will usually 'pull the codes' for free.   This will at least give you some idea of what might be happening.
#744 of 1085 Mercedes 190 E by lokimicfurt Apr 05, 2007 (10:48 pm)
I just bought a used 1990 Mercedes 190 E from the original owner. I was warned not to use one of the back windows until it was checked. Sadly my idiot sister rolled it down and now I can't get it back up. It's electric, runs awesome..it just has this one window problem. How can I fix it myself? Or am I going to spend oodles of money to have a mechanic doodle with it? =/ Replies to this message: burdawg (Apr 06, 2007 5:17 am)

Replying to: lokimicfurt (Apr 05, 2007 10:48 pm) If your mechanically inclined, you should be able to fix it yourself. Most likely the window regulator is bad but it's hard to say for sure. You may be able to get it back up if you take the door panel off and push it up from under the glass while someone works the control (be VERY careful!). If that works then disconnect the motor until it's fixed. When I had my 280 I remember doing a lot of regulator repairs. The motors never seemed to wear out, but the regulators where weak and would tweak out of shape after a while.
