Random glitches ( windows, radio, locks etc). Sometimes they work. What works changes daily. What would cause this?

Hello,

This is common when the TIPM goes out. It is easy to replace because it self initializes. Here is the instructions in the diagrams below on its location and how to replace it. Check out the diagrams (below). Please let us know what happens.

As Ken said it is likely the TIPM. AKA the smart fuse box. What you can try before replacing it would be to remove it and check the connections on it for corrosion or other damage. Clean any you find off and apply a light coat of dielectric grease and reinstall it. Test it and see if it now works.

Thank you so much!

I will give it a try.

Is this part expensive?

Usually you can get them from the dealer for a couple hundred dollars or try to find a used unit at a wrecking yard. Please let us know how it goes.
