well my trucks been running great since ive changed the converter and put a flowmaster on it. but for some odd reason my fan only runs on high and my a/c pump isnt kicking on. So im dumbfounded to what it could be. I have a dual fan set up with a Nelson harness that ties into that lil green wire for the a/c and pin 42 on the comp. the truck was tuned for elec. fans. I checked every fuse every connection and cant figure anything out. Any one that could possibly through me a bone it would be great. thanks guys

 

Do you have a check engine light on? And is the fan always on?

 

no check engine light but one fan is constantly on high (seems like its high) all the time

 

when i mean on all the time i mean when its running depending on how long the trucks has been running it stays on for a period of time after i shut the truck off

 

well i just got home from truck night in Yankee lake ohio and was hopen there would be more of a response to this. Oh well thanks. Its prolly how the harness is wired or a pinch wire.

 

if i disconect my electric fans from my truck and reinstall the clutch fan will i need to retune the computer for anything?

 

I HAVE NO POWER AT THE A/C PUMP. check the connector with the key on the run pos. Nothing i took the fan outa the loop to see if that was the case nothing. so the fans in the right spot. Checked the pressure switches connections seem to be fine. Maybe im outa refrigerant :-(
