Myriad of sudden electrical issues.

I'm working on a tablet install and somehow lost turn signals and hazards. I chased the rabbit and two blown fuses later I have hazards... but no turn signals, no A/C, no Cruise control, and my check engine/maintenance lights are on.

I've removed my additions to limit variables in this cluster and would just like to get back to stock for now.

Description of problems:

No turn signals. While the hazards will light the dash indicators and outside bulbs, the turn signal lever will do neither. I've replaced the relay thinking it might be "half bad" but to no avail.

No A/C. The panel will illuminate but I get no response from either of the buttons when pressed. All of the fuses under the driver's side dash and behind the battery appear good. I've even gone so far as to switch my MG CLT relay for the towing. Nada.

No Cruise Control. The dash indicator illuminates but the button no longer "sets" the speed as it used to.

First the maintenance light came on and the check engine soon followed. I have an ODBII Reader arriving today. I'll update with codes as soon as possible.

In the mean time I'd appreciate your input on how badly I've f-d up. I have a sneaking suspicion that I've fried one of the internal computers some how. Thanks for your time!

EDIT: I forgot to mention that it won't shift out of park without use of the little cheater button near the shifter.

 

Check the IG1 fuse under the dash on the left behind the small cubby.

 

You might also check for terminal corrosion on your battery and ground cables.

IGN 1 No. 2 fuse. Just replace it.
