Coolant Fan/ Ac issues
I have been trying to get my 86 berlinetta up and going for quite some. I recently was working on my Coolant fan wiring. Everytime I would turn the key the fan fuse would blow. So while i was swapping my 383 in I cut the two black wires to the fan and wired them with add in relays to the fuse panel to get the motor going. I decided this week to fix the original fan wiring and found that when i swapped the big relays under the hood by the brake booster the fan fuse would not blow. I decided that the relay was bad and so i got one from autozone. I reconnected the fan wires and now the fan turns on with the key, but now I have created another problem. My ac compressor is now not getting any power to it. The low pressure ac switch on the drier is not getting power either. This is very perplexing as all I did was swap some relays around under the hood. All ac controls on pod works fan speeds all works just no power to the compressor or pressure switch. Because I swapped in a different motor and carb there are very few sensors connected just the oil pressure sending unit, low pressure ac switch coolant temp sensor. Why would only one wire be affected? Any help would be appreciatted!

Using a voltage tester, with the key in the run position, AC requested, probe both sides of the AC mode switch.
One side the wire is brown.
The other wire is light green.
Was there voltage on any of those 2 wires?

When you see fog or “running” lights on in good weather beware. WLow performance driver ahead.
