heater blower not working

[eefy]

hmmm think i've got the same fault, blower motor working for a few mins that stopping, the heater matrix is fine as theres still heat coming out.

think i'll replace the same relay and see if it solves the problem :)

I think it's worth checking the switch first - I've had an intermittent blower fault for some time (position 3 didn't work at all and 2 would sometimes cut out) and found that the switch wasn't connecting reliably, pushing on the switch results in the blower working again (until you release the pressure that is).

Might be worth removing to check the connections and giving it a squirt of WD40 or similar - none of the switches on my old Land Rover worked when I got it but WD40 and operating the switches a few times fixed them.

Nooooooooo! Wd40 is evil! Use proper contact cleaner, and proper penetrating oil, not one spray that tries to do everything

edit: I don't mean fill your switch with penetrating oil by the way

[marcus]

Ok ok, replace WD40 with [insert your favourite contact cleaner/penetrating oil - delete as appropriate - here]...

Any joy Eefy?

I've got the same issue

Effy had a dodgy switch, I sent him my spare and it solved the problem.

Ian - you're a one man solution factory!

cheers for the heads-up - I've ordered one. hopefully not too difficult to fit

[ianaudia4]

Very easy to fit Rick, a couple of small screw drivers and 5 minutes of your time.

think i might have cracked my heater blower problem (sorry for thread hijack)

took the scuttle panel off today and poked at the wiring on the side of the fan unit. the blower instantly started up.

i tried again, just poking the brown wire. that worked too. then I blew the fuse!

so bad earth (my car is bloody full of them!) haven't worked out how to fix this yet - but i'll report back when I can

Shame you are where you are mate as like I said I would have loved to have helped you with all the little niggles.
Try cleaning up all the earths and re-attach securely, changing any that are past their 'best before date'!

That's the way mate, a systematic approach. Get down the pound shop and buy some little wire brushes.

had another look at this today

although if i twiddle the wiring it makes the fan come on, it still cuts out eventually.

And today when I was peering into it, it started smoking slightly!

so does this imply that it's overheating and cutting out as a safety measure?
