I have an '86 LTD crown vic that has intermittent window problems. When it is extremely humid and hot the windows will not work. When it is cool & dry they work. What would cause this & what is the fix. When this occurs, all windows are affected and none of the switches work. Thanks Edited to be more clear. |
| I am not a mechanic, but i have replaced the driver-side window motor on my Olds Cutlass. Is the window on the driver's side? Since you use that side for up and down and also the vibrations from opening & closing the door, that motor will most often fail first. I think you are experiencing symptoms of impending complete motor failure when it won't go up nor down no matter what the whether, double-ck with someone else. |
| If it were just one window, I would say check and clean the contacts on that particular doors power window switch. But being all of the windows, check your ignition switch. A faulty ignition switch can cause intermittent problems with power accessories and A/C. These are inexpensive checks before you delve deeper. |
| Sounds like the window control switches on the driver side. They are the master switches that control the functions of the other three, so if it goes none work. Possible the years of age, use, dust, and normal spillage of water and drinks have taken thier toll. I'd tru that one first. Most auto supply stores should have them, very easy to replace. Good luck.... fullclip |

I just replaced the driver's side switch on an '85 Pontiac. It was giving the kind of symptoms you describe, maybe a little worse. The oldie looked like it had about twenty cups of coffee spilled in it. I'll guess the humidity affected the coffee creamer residue??!!?? $37 for the generic GM switch. Ford? |
| Gun-fan: Most likely the main switch. But that will only be suspect if the windows work fine under the same conditions using the individual door switches. If you can operate them individually by using each door's switch but not from your controler on the drivers side door, it will be the main switch. It is almost impossible for ALL four window motors to go unless you suffered serious flood damage. I would verify if they work from each door and then check the main switch again. But keep in mind that on some cars the individual window motor switches will not work if the main switch is faulty. Pull the switch out and check the harness going in. Make sure the connection pins are not corroded which is common on main door switches and that it is snug. Also look at the harness going through the door into the dash from the outside. Check for juice at each switch terminal on the main harness, with the key on. Make sure the wires are not crimped or cracked. This is another common problem, but due to the tight work space and the thick rubber covering it can be difficult to look inside the harness to check for split wires. Let me have some more details and perhaps I could steer you in the right direction...Good Luck |
