Dual cooling fans. The AC compressor don't kick in when I turn the AC on. Neither does the passenger side or driver's side.

 

Not trying to be smart-***, but is this the same song second verse of the wiring harness
issues in other threads?

I'm tellin you dude, Service Manual w/ total electrical system info will be money well spent.

 

I have a GM Service Manual, What's your Engine VIN?

 

This is has dual fans...

 

the fans are in a 89 formula 5.7 car. The mess of a wiring problem are in a 88 Camaro with 5.0tbi. I would love to get a service manual for all 84 to 90 Camaro and firebird. Even one would be great. I have no credit cards but Lowes and don't know how safe debit card is. Or if I can buy with that.

 

Not sure if these are still valid

You scrolled right past the helpful information, that I offered out of my GMSM without acknowledgement. And yes I am being a Smart-A$$ because I tried to save you time and a buck... I chose that diagram because VIN code 8 is much better known as the L98 5.7 V8 TPI, standard in the 1985-91 Corvette and optional in the 1987-92 Camaro/Firebird platform which if I'm not mistaken is what your asking for help with.

Hope it helps...

According to these diagrams, there can only be a few problems. sensor, wire, fan motor, relay, ecm
