Who has GM Electrical Service manual?

Look up something for me. My High blower fan wasn't working. Finnaly traced it back to a loose electrical connection on then distribution block on the fire wall. Some stuff to run a trailer including brakes was added to my 88 Burb. They didn't get that left nut tight so it had an intermitant connection. One of those wires goes to the blower. There is a second wire that runs down the fire wall and goes into a harness. Look up and see where that one goes to. I'm beginning to bet the transmission is tied into that.
Thanks

Well at least it wasn't something like the ECU.
Thanks.
You think the AUX cooling is the rear air or the electric radiator fan?

I own Helm manuals from 1973 thru 1999....C_K_R_V. I also have the electrical diagnostic manulas from 87 to 91...

Most if not all R-V big blocks from 87 thru 91 recieved the cool helper fan..
