Combination of Electrical Issues

Excuse me if this problem has appeared on here already, I have done some extensive searching but cant seem to find this same problem anywhere.

I have been experiencing intermittent issues with my 2008 Commander. This morning I had my air conditioner on and all of the sudden it shuts off, the blower and all just died.

I began to look at my dash and my compass just has "--" where the indicator would be and then my airbag light came on. I was trying to find a decent place to pull over and check things out when after about 30 seconds after everything quit, it all came back to life as if nothing had happend before.

I am thinking that its almost like a relay or a resistor getting hot but at the same time I am not sure how the blower, air bag, and compass could all be tied into the same problem.

If anyone has any help it would be greatly appreciated!

Have your battery tested.
I have the identical problem. I checked codes. There were many indicating various components lost communication with the parking assist module.

@CSegroves ;

You may consider a trip to the dealership & pay the $120.00 to have the park assist module tested; It could need to be replaced.
I bought the lifetime warranty when I purchased my Commander. I did ask the dealer to look at the problem when last there. They could not replicate, so did not troubleshoot further. My problem has happened every time I drove for the past couple months, until after The heavy rains this weekend. Probably coincidental by curious. If I could locate schematics I may be able to dig deeper.
The only mechanical problem I have had was a leaking water pump. Not bad for 240000 miles. I have had to replace the drive train computer twice (intermittent knocking and engine dieing). It took the dealer over 3 months to find, since it only happened when the engine/transmission was hot. I'll post the cause when I find.
Thanks for the input. I will do this test.
I have not. The dealer can't find it either. They suggested to jiggle the key when it happens. The ignition switch is sometimes not fully engag
