Default Heater blower wiring problem

I am in search of a wiring diagram for a 95 Discovery I just purchased. Bought it knowing the clutch was out. Thanks to the help of this site I was able to install a new clutch kit by myself--not without a lot or work though.

As I was putting everything together. I noticed that at times had power to blower fans then no power. I am a electrician by trade. Main fuse under hood good. Have power to fuse under steering wheel. No power at all to fan switch and cannot hear any relays clicking when turning on fan switch. I know its not the fan as no power there. Would love to get my hands on a wiring diagram to trace things out. Any suggestions in any of these areas would be appreciated.

Thanks,
Ken

The RAVE is the factory set of tech manuals, including circuit diagrams. The 95 is there. You would want page 275 of 734 in the circuits manual for the 95 for heater fans. Page 337 of same for the cooling fans in front of radiator and condenser. Wire color legend is at the front of the manual and wires have letter(s) to signify color. One link is http://macassemble.com/lrm/discovery...g%20(1995).pdf

8 calorie arc flash rated clothing is not required. Note - polarity important, my previous owner had replaced fans (wire is under top lip near battery) and reversed them, they blew out the grille and I had all kinds of overheat at idle.

Default problem fixed

hey everyone. Thanks for the help and the wiring diagram. Problem was a bad relay. Ignition relay number K-127 was bad. Happened to have an extra relay around from when I was rebuilding a 77 MGB. Have heat now.
