O.k.,I will take a look for some bulletins and electrical info on this system here.I will post back here shortly.

Customer: replied 20 days ago.
I'm sure it is a fuse or relay in just need to know which one
Expert:  peterpete190 replied 20 days ago.

O.k.,the mirrors and windows are controlled by the General control module.This is a very common component that fails out of the blue like this here.It is so common there are companies that will actually rebuild yours instead of having it replaced.They will usually also walk you through removal and installation for it.Below is a link to one of these facilities that can repair your general control module.If this occurred out of the blue and nothing was used when it occurred and with the very common fault of this module this isnt a fuse or relay fault.The general control module has built in relays for these functions here to control the windows and various other electronics.Some of these electronics are listed in the website info below.I have had to either have this repaired to correct this issue or removed and replaced to correct this fault here in the past before several times.

It's called a "general control module"
Where can I buy this part?
Expert:  peterpete190 replied 20 days ago.

You would need to purchase it new from a dealer or in some cases you can purchase it rebuilt from the company I listed above in the link I provided.But it is a "general control module".

Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.Your 5 star rating is appreciated

Thanks Pete

Customer: replied 20 days ago.
is this it?
Expert:  peterpete190 replied 20 days ago.

That is the module.You will need to have it programmed/coded by a dealer or authorized repair center after install.

Thanks Pete
