Air-con and blower motors not working.

While looking for the dim dip module I appear to have dislodged a connector or blown a fuse such the heater blower motors no longer work. All visible fuses are intact, I assume there must be others else where. My landrover falls in the up to '95 according to the manuals but they don't show wiring info for pre '95 with air-con.

The fuses for the air-con are on a seperate module, I guess there's a relay somewhere, any idease where?

All sorted.
When I was looking for the dim dip device I had disturbed the under bonnet wiring looms. What I didn't know was one of these contained the fuseable links. In moving the harness I accidentally broke one of the links which just happened to supply the heater lower motors and air-con. When I undid the harnes I found that all the crimped connections for all four links were severely corroded. I have repaired the broken link and plan to arrange a permenant repair to all the links.
I would advise anyone with an older Discovery to check these for corrosion damage if any circuit unexpectidly fails.
