Genius - just genius! Thanks!
Would I also have to attain a doctorate in order to be this electronics-friendly...? (Just want to know how long I still have to go)!
You're assuming that I have a manual! Manuals are for mechanics and for people who want to work on their own cars!
So, OK - yeah - jumping the two wires from the back of the thermo-switch, triggers the fan! It's getting the right signals - bad thermo-switch then!? Now, here's your favorite question Jes - "WHY"!? I mean - it worked just fine when the car last ran... Any fixes for it, before I replace it? I'll check resistance between the two connectors on it (but here again - the assumption is made that I actual own a multi-meter)! I'll get to it later today and report back!
I'm also going to check that little red LED on the dash and see if the bulb is out, or what!? Wonder how I can test it (and the sensor) first, before pulling the entire bloody instrument cluster AGAIN...!?
