Help! I don't want to freeze!

As title... keep popping fuses in my heater fan - 1989 lr90 - I'm guessing it's shorting out somewhere... Is there anywhere that these are prone to corroding/ damage, that I can check first? Or have I just gotta jump in there with my multimeter and torch?
Cheers!
Plank.

I'd get in there with a meter and test lamp and establish what exactly is causing the short, could be a wire rubbing through some where or water getting into the components. Once you find the fault, investigate why and fix it.

Try unplugging the blower motor and replace the fuse. If the fuse doesn't pop then your problem is the motor. Easiest way to test the motor.

Pop the dash binnacle out and look at the switch wiring, its pretty crap and very exposed to the moving parts of the switch

That's the plan! Was kinda hoping there was a problem spot that I can hone in on. I'll get in the garage this eve with my meter! Cheers!

Thanks! I'll pull my dash out later on aswell. gonna test motor first as it's less fixings (yeah I'm a lazy basta*d - or 'efficient' as I like to refer to it as )

Thanks all for your help!

Dash binnacle is only 4 screws and a pair of long nosed pliers to pop the speedo cable off, if it takes you more than a minute your slacking!

I've been slacking terribly. Been chopping up this winters wood, bit later than I should have done that to be honest! I'll get her in the garage tomorrow after work and pop the dash off (Mine only has 2 screws holding it on anorl!) haha

Mine was blowing as well, it turned out to be a seized heater motor, swapped it out with one from on line breakers parts gateway, not too bad to fit.

Heater motor is usually sitting in a bath.

I've deduced that it's definitely the motor, and providing the Mrs doesn't have plans for my evening *wink wink* then I'll be in the garage fixing it! Trouble is my landy doesn't quiet fit in the garage so have to do a half in half out job which is a pain.


Thanks all y'all for the advice!! I'll let you know how it goes this evening!

Take the grill off the wing and make sure the fan is not obstructed with mud,crap etc.... and spins freely

Mine had stopped working as it was full of water. Drain in ducting was blocked with afghan sand letting the water build up. When I fixed it all I did was clean out, spray with wd40 and drill a small additional drain hole in fan box just in-case.

Removed all the grills on my wing, emptied out the bath of water in the bottom and cleaned the drain hole. Fan was solid so soaked in wd40 from the back of the motor (just! Required some gentle persuasion of my snorkel attachment on the inner wing - rest of my snorkel is not fitted) and woohoo! It freed up! Spins like a beaut now. If anything it's better than before!!! Thanks again for all the help and advise, as always much appreciated!

Heater still going strong, I'm hoping for lots of snow down here now!

Did you fan not turn at all with the water there.?! Mine to us full and not working, although I can turn it by hand. I just assumed that the motor was knackered.?!
