[modern] Circuit failure warning

Dear listers. Having taken the plunge to replace shocks & bushings fore &
aft as well as brake accumulator & switches on my '89 VDP I discovered a
whole new ride. (and halt)
My problem is a “circuit failure” indicator that just reared its ugly head.
The blower just spews very hot air with no control over the temperature, the
door locks won’t operate electrically and the seat belt “strapper onners”
don’t work.
If I open the sun roof and windows then push the dash “Lock” button, the
windows and sun roof close.(nothing from the locks)
I checked all fuses that I know how to access and they appear fine.
This has me truly perplexed and I welcome any input.

Respectfully yours.

Peter Janssen. '89 VDP
