Electric Window Failures by gift0025

All of the electric window failures have been due to a part called the "regulator assembly." No motors have failed. Very few independent repair shops will tackle this job and apparently cannot get the part except from Ford. Two hours of labor are routinely charged plus the cost of the part plus a surcharge for shop rags, screws, chemicals, etc.

Window Regulator Repair by 427435

I had to repair the driver's door window on my '93 Marquis last year. The regulator cost about $75 and the worst part of the repair is getting the trim panel off the door. I can't remember for sure, but you may need to drill out a rivet on the window lift mechanism and replace it with a short bolt.

electric windows by sergeis

Obviously those garage guys are not familiar with electronics. I am sure anyone familiar with electronic circuit and basic knowledge in electronics could pinpoit your problem easily. Does the same circuit drive all windows? Does it fail at the moment when you actually move one of the windows? Is it always the same window? Is it constant voltage or constant current regulator?
Obviously the regulator is OK, and it burns because of something else, it might be abusive load (motor takes too much current, something wrong with it, or there is an occasional shortcircuit in wires, though the circuit must have electronic protection for that), or the power which comes to the circuit is not normal. If it is under computer control (most probable), then the computer program itself may abuse it by continuing powering window while it has reached the limit. Anyway, the circuit is not the problem. It is like keeping replacing flat tire while your garage floor is full of loose nails.

Window Regulator by 427435

Sergeis, you may know electronics but not Ford's terminology for power window components. The device that failed in my power window, that Ford called a "Regulator", wasn't electrical. The part was a drum with a steel cable wrapped around it and the cable was kinked and not tracking on the drum. Yes, it was driven by an electric motor but the motor wasn't the problem. When I told the partsman what I needed, he said, "Oh yes, you need a regulator assembly." He left me with the impression that he had seen this problem before.

I see. It is just that I still had no problems with GM '95, didn't need to learn Ford's terminology. Hope to keep it this way.

Does anyone know if there is any truth to the article in Motortrend.com about a souped-up
Crown Vic named the Blackhawk? Will it be built
or will we have to wait for the Marauder?

92 Crown Vic 4.6L stumbling and bucking under light throttle. by neanderbob

Hello all! I need some help. I've got a 92 Vic with the 4.6L, 235,000 kilmetres on it. I love it to pieces but lately it's become almost undriveable. It bucks, bangs, lurches, and shudders under light throttle. To get past this point you have to floor it for a downshift. I can't even tell if it's the engine or transmission doing this. Full throttle is great. It seems to be worse when its hot. It acts the same in "3", and overdrive. Recently ALL fluids and filters have been changed but the problem didn't start for a few months afterwards. Also I would like to know what fuel is recommended and if it can tolerate an ethanol blend (having trouble getting an owners manual). Any advice would be much appreciated! Thanks for your time.

Stumbling Crown Vic by 427435

Neanderbob: Is check engine light on? If so, take it somewhere where they can do a computor scan.
 
If it stumbles at idle but not full throttle, some of the possiblities include:
--A vacuum leak.
--A bad air flow sensor
--A bad throttle position sensor
 
If you haven't changed plugs and wires, it might be worth changing them, but, if they were bad, it shouldn't run well at full throttle either.
 
Good Luck.
