Power window

atmk631 · #1 03-25-2007, 06:28 PM

I have a power window problem that I can't seem to solve. The driver's side window wasn't going down only after the car was started. Sometimes it would work right after starting the car, other times it took up to 20 mins for it to work. It would continue to work perfectly until the car was shut off and left overnight. I tested for power at the motor and it was fine. Therefore, I changed the motor. SAME PROBLEM. Then I checked all the wiring and connectors from the door into the car. All seems OK. The window is not binding because I checked that when I changed the motor. Any Ideas would be appreciated.

Sounds like the accessory delay is causing some sort of problem here. Do any other windows work?

Every other window works fine. I thought it might be the accessory relay as well, but I thought it would affect all the windows at the same time? Maybe not.

What year is your Taurus, and is it a sedan or wagon?

It is a 2003 SEL Sedan.

I agree with you that the accessory delay relay should have the same effect on all windows. I wonder if you might have a problem with the One Touch Down (OTD) relay or circuit. It appears that there are some resistors in that circuit that may have gone high in resistance and may be limiting the current to the motor. I'm nto sure how the OTD is activated in teh 2003, whether it is by holding the button down for x seconds, or pressing it twice, or pressing it down a bit further, etc. Maybe you can attempt to not use the OTD feature and see if that makes a difference.

The OTD is activated by pushing further down on the switch. I have taken apart the switch and isolated the OTD, but the window still acted up. It must be a relay (or something similar) that is not activating right after the ignition is on. And one that only affects the driver's window. I wonder if the Accessory delay seperates power for the driver's window?

Nope, the accessory delay relay provides the power to the master window switch as well as the individual door switches. It also powers the switch illumination.

Looking over the diagrams again quickly, it certainly looks like the OTD relay would be the likely suspect though. "Regular" window power when the OTD is not active is still provided through a normally closed (NC) circuit of the OTD relay. Maybe the NC contact is intermittant. It looks like it would either have to be the OTD relay or the Generic Electronic Module (GEM). The relay would certainly be less expensive to start with then the GEM.

go to a junk yard and get a replacement switch console for
the door.....its cheap , easy to change and the likely problem.
I had simular problem with 2000 model, the junkyard part is
working great.......I think the new part in autozone is only about $50

I am having a similar problem with my 97 Sable wagon. Both rear windows quit working from the driver's switch and rear door switches. I removed the door panel and started checking circuits. I was measuring 10-11V at the motor. After charging the battery and starting the engine the two back windows started working again. Then yesterday the right rear window stopped working again. I tried it with the key on and nothing, started the engine and it worked! It's a weird mystery.

I purchased an OTD, it is the same part# as the delay relay and two other relays in the fuse block. Anyway, I replaced the OTD and the window has been working fine for the last six days. Either it is behaving itself or the problem is finally fixed. Thanks for the help.

Did you compare the voltage at the motor against the voltage at the battery? Doesn't really sound like a mystery, sounds like you either have a battery that's about to leave you stranded (and probably take the alternator out with it) or a high resistance path somewhere (ground maybe).

If the battery voltage with the engine off measures 10-11 V, replace the battery. The window regulators may have dry grease in them now, increasing the load on the motor enough to trip the circuit breaker with the low voltage condition.

If the battery voltage is more in the 12.3 V range, then the problem is probably a resistive path somewhere (switch, loose fuse, ground, dirty connection).

I spoke too soon. It worked for one week and now it's acting up again. This is what it did before, worked for a while and then didn't. I don't think that it is the switch because it only occurs after start-up and at no other time. Does anybody have any more suggestions? They would be appreciated. Thanks

How regularly did it act up before? If the issues seemed to change with the new OTD relay, I'd still concentrate in that area. Make sure the contacts are clean and fitting securely. Check the voltage levels at the terminals to make sure you are getting a good ground, strong coil trigger, battery voltage where there should be battery voltage, etc.

Sometimes it would work well for a few days and then act up again so the new OTD may not have helped the issue. I Just checked for good ground, proper voltage, etc and everything seems fine.
