Hi

On what appeared to be the hottest day of the week, my drivers side window failed to work.

This implies:
Fuse is OK since the power window on the passenger side works
Relay is OK since the power window on the passenger side works


I can clearly hear a clicking noise when the button is pushed to lower the window. I believe this means it is receiving power.
There is no movement on the drivers side window.

I took off the door panel, not sure what to do next,
any ideas?

 

Your answer will be posted shortly and I hope all goes well. What a pain no doubt

 

Sounds like a bad window motor to me. You can try tapping on the motor but that probably won't work. If you have power from the switch to the motor that should be the issue.

 

and he's a Ford mech so he's in the know

 

I found an OEM motor on ebay,
Any reccomendation? Perhaps something in Canada?

Scrap yard would be your next best bet or find someone parting out a car now.

 

I'm not a tech but have been working in dealerships since I was 14.

 

I stand corrected, oops sorry lol. X2 on the scrap yard

 

Interesting enough, the power window has been working perfectly fine for about a week now..
Perhaps tapping on the motor resolved the issue, for now..

 

thats good to hear. I remember my old 82 GP used to give me fits with the windows
