Re: Fan Fail Relay



You're right, Harold, the rewire of the A/C and cooling fans works 
great. I have your car! I was shocked when I learned that stock 
DeLoreans cycle the fans an/off with the compressor.

Buried in all the misc. papers I received with my DMC was a set of 
instructions and diagrams explaining this wiring modification. I 
have scanned both text and diagrams, cleaned them up a bit, and put 
them in the Files section as "acmod.pdf".

Personally, I would recommend a drop-in solution like the FanZilla, 
but this mod can be done with minimal expense. Also, for those of 
you that have discovered you have this modification, here is the 
description of what was likely done (since this was authored 20 
years ago and was probably passed around amongst Houston-area 
enthusiasts, at the least).

I hope you don't mind, Harold, but I left your name on it. :-) 
You're free to review it and pass along errors or corrections and I 
will update the file.
