So I recently purchased a 1994 C1500 Extended cab. Previous owner did an engine swap to another sbc 350 4 bolt.
I am having an issue where the wipers do not function in any capacity including sprayers. On top of that the drivers rear brake light and turn signal is not functioning but with the lights on the main tailight functions but still no brake light. Bought the truck with no ac hooked up and i know the blower motor is shot I assume thats not related.
I have:
replaced the wiper pulse circuit board.
Checked all grounds on the outside of the truck and found many that had failed or werent hooked up and replaced them including the one in the rear by the tailights on the frame.
All new headlights taillights and boards
Replaced headlight switch
Went through tailight wiring and repaired the issues i found.
Obd port ground is good as well but i do see a disconnect ground attached to the hood latch pull and not sure where to connect that. I cannot find any more ground locations under the dash to check.
I checked fuses and dont see any issues.
Passenger tailight functions as it should and so does the third brake light.
The cluster speedo battery and gas gauge work fine but no tach, no engine temp or oil pressure likely due to the swap.
Not sure what else to look for if figure out but this is getting the best of me and I have search the forums extensively looking for the cause/fix.
Any help is greatly appreciated!
