Heater blower fan location

Gixer1985 · 2022-02-13 11:47:14

Hi everyone

So heater fan blower has stopped working.

I've checked the contacts on the slider seem ok.

Any ideas were the fan is located I've tried searching under the centre section of the dash but not sure what I'm looking for

Any pointers greatly appreciated

absolute bu*tard to get to behind "glove box", in front of firewall (see where coolant pipes go to from the engine bay), good luck!

Thank you

Luckily it's not got to come out

Issue is the earth wire has corroded off. Some one has bodged it in the past

Phew an easy fix for a change ?

hard to get to? not that badm you can do it all from under the dash.. glove box out to so you can see, and its 3x 8mm screws to drop the motor.

i did install air conditioning to mine, so i have 2x blower motors! its like you are in a wind tunnel. the 2nd motor sits back from where the bonnet pull is with a duct going behind the steering column support, and yes that is a bit tight!

This has become my next job. I don't know if it's packed up or has some wiring issue. Going to blast the switch out tomorrow with some wd-40 and see if that fixes it. If not, well it's check the wires, then move to the blower.

My van has air con, not that I've ever used it, so will there be a second fan or was that specific to your build style, John?

If it has aircon it will have 2 blower motors. its possible that only one was working to start with and now that has failed.. however do try cleaning the slider switch up. thing is though they usually fail gradually.

It's acting weird. So it hasn't failed apparently, at least I don't think the issue is the blower, per se, as it suddenly burst into life yesterday at full power. At other times it seems to run at different levels, almost like as I rev it and the amps increase, so does the fan motor speed. This week I am going to try and check the wiring on both the switch and the blower unit. I have this nagging feeling that the issue is electrical. Maybe a bad earth or something else like that. I( also wondered if the battery was the issue, but fans really shouldn't be pulling that sort of amperage. I don't use the air con, I think the last time I depressed that switch was the day i bought the van, just to test it worked, but I've not used it ever since.

if you jiggle the speed slider control does it change?
my money is on the speed selector slider acting up. you can take it out and clean it but its more easy to just replace the whole unit. being all electrical it does make it more easy. there will be loads about if you hunt for one.. old taxi repair places, general scrap yards, facebook, ebay..

So the saga continues. Sorry I didn't reply, i've been offline for a bit.

So I cleaned up the switch. So when the blower works, so does the switch, but it doesn't appear to be the issue. I found a weird thing with the blower. If I've been driving in it for say 20 mins and then reverse into a space and then put the handbrake on, the blower starts running. So to confirm it. At my house, I put it in reverse, disengaged the clutch a little, then put the handbrake on and took it out of gear, in that order. The blower then sprung to life. It doesn't work if you only do one or the other. Also if I disable the VSR between the vehicle battery and leisure battery, the reverse/handbrake thing doesn't work.

So I have no fkin clue what is causing it. I am thinking electrical issue. Could a bad earth or connection be the issue? Either way it looks like I need to remove the dash. But with the VSR thing I'm wondering the leisure battery side is causing the issue. I did put a completely new earth in for the LB side (bolt through a steel panel with paint removed to allow good contact, then wired into a busbar). But I do, do something weird with the solar controller. I have two outputs on the controller, so I send one to the leisure battery (70% of the power) and I put the second on the other side of the VSR so I can back charge the vehicle battery (30%). I wonder if that is an issue.

I think you need a priest!

I have the same van and had the dash off umpteen times when
sorting the heater out.
Its pretty easy to do with a T20 driver IIRC and the heater looks easy enough to access

Yeah this van is definitely up there for in need of an exorcism.

I'm hoping this isn't the start of a loom/old wires issue. I think you guys warned me of such a thing when I first joined and bought the van. So far it's been pretty bulletproof, until last April, then things started to go wrong.

I had a few issues and never got mine off. I removed the radio and basket thing for it (I wondered if this caused some of the electrical issues as I found several wires with screws holding them in place behind the radio), removed the seven bolts under the various panels, removed the instrument display, but it seemed almost like I'd missed one at that point. But i'm sure John said there are only seven bolts holding it in place. Maybe there is an eighth bolt. I think I got them all though.
