#2 of 246 Hazard flasher relay
Jan 02, 2006 (2:26 pm)
Where is the hazard flasher relay located on a Grand Marquis, 1997. The under dash fuse box has a round space, but nothing is plugged in there, and there is no info in the manual.

it is on the opposite side of the panel. You gotta flip and twist it down to view the fuses on the back of the fuse box
#4 of 246 GM windshield wiper control stick

I have a 98 GM and the wipers do work at times. I know it is the turn signal stick control. How does one take it apart and is it small gears in the arm which are worn? I know the dealer will have a field day charging a fortune. However if it is too tricky to fix myself I will have no choice.

The air intake system on my 2000 Grand Marquis will begin to crazy when the weather is cold (and runs fine when the weather is above 50 degrees or so). The engine doesn't seem to be reving, it is just that it is sucking in much more air, creating a loud humming sound and causing the car to spring forward. With the foot off the gas, the car cruises at about 30 mph!! If I give the gas peddle a quick push, the reving/humming will stop when coasting, but come back immediately when given even a little gas. Also, after the car comes to a complete stop, the engine will return to normal/the air intake goes back down and the humming stops.
If parked outside, this will occur within seconds of starting out. If parked in heated parking, this will occur after 15 or so minutes of driving. Replacing the air filter had no effect on all of this.
Any ideas what this could be, and how to fix.
Thanks in advance for any help out there!!

its not your air intake, its like an throttle position problem, most likely your Idle speed control solenoid. and maybe the TPS sensor, ECT sensor. If you got a code scanner, check it out and find out what itmay be. if not pay someone to find the code.
I had that problem in my car an 1987 GM and it was the Engine cooling temperature sensor. It was plastic no it offered a weak ground and always sent th computer into run hot mode. Making the car idle like a bitch and allowing the car to accelerate because of the higher idle. I also had the problem in an 88 TC I had and it was the TPS. I had the problem in an 84 CV and it was the electronic choke on the Throttle Body FI Carburetor.
#8 of 246 1998 grand marquis, check engine light/ rough idle ?
Mar 08, 2006 (7:23 am)
I have just bought a '98 GM,87K,2 weeks ago. It has run smooth till today, doing 50mph, check engine light came on but car still ran ok. Although, I noticed a rough/uneven idle and a possible slight misfire at 5-10mph, although still accelerates smooth. Any ideas anyone? Thanks (p.s. it was raining heavy).

The last time my 4.6 had those symptoms it cost me $742.45 at the dealership to install new plugs, wires, O2 Sensor, fuel filter, & fuel additive to the tank. Fixed it.

Sounds like plugs and/or wires. If the wires are original, cannot hurt to replace them. Also could be one of the coils is misfiring, which is what replaces the distributor.
To me, it seems to be something in the ignition system. It is a pretty basic system today - I suggest finding the garage that your local police force may use - they will know a Panther platform very well.
