Heater help please

Mick Guilbert · Oct 6, 2015

Hi All Gurus
The heater blower on my soft dash does not work, so looking for some help.
there is lots of info about heaters, resistor location,fuses etc on the older classics but I can find very little about the soft dash. Mine is a 94 so any help or advice would be great, the blower does not work on any setting and have been told it may be something other than the resistor, where would I start to look?
Regards
Mick

Does your air con work?

Mick Guilbert · Oct 6, 2015

Hi
My truck has no air con sorry should have said it is a 300TDI.

The heater and air con share a relay and the control switches. I'd start there. Another question. Is your cigarette lighter on the console working?

Mick Guilbert · Oct 6, 2015

Yes cigarette lighter works ok, where is the relay?

West Slope Rover · Oct 6, 2015

I have to ask. Did you check the fuses?

Mick Guilbert · Oct 6, 2015

Yes the fuse box to the right of the steering wheel, all fuses look ok, will replace fuse as a matter of course though.

he said he hasn't got aircon.

The Aircon has 2 relays, one connected to the heater fan and the other to the aircon switch, the relays are earthed via the trimary switch and supply power to the Aircon pump and the cooling fans.

you say no setting on the fans work - unlikely to be the resistor network then as one of the settings bypasses the network.

The heater/air con load relay is found behind the trim panel on the right side foot well. It is the second one in. You can test it or just swap it with another relay to see if that's the problem.

That's great I will try that, it also makes sense as the carpet was wet when I got the truck.

Is the Rangie new to you?

Mick Guilbert · Oct 6, 2015

Yes I have only had it 2 weeks, have always run series Landrovers before. And they are simple to repair.
This one is in excellent condition but does have a couple of electrical issues.

You have moved on to a far different beast. Although our old Rangies don't compare in complexity to the newer versions, they are overly electrical, I guess you could say.

Oh, you should check to see if the water is just water and not coolant.

Mick Guilbert · Oct 6, 2015

Thanks for that, the water is not coolant as the level has remained constant since I have had it, also smells like water not coolant. Did worry heater matrix had given up though.

to be sure of coolant level remove the bung on top of the thermostat housing , it should overflow , level in expansion tank doesnt mean engines full

You have a leak that may be running down the back of the dash to the floor ...

Take the carpets out, if only to dry them out properly ... and look for evidence of water run

youd have to strip most of the interior out

Mick Guilbert · Oct 6, 2015

Thanks guys will check that.

Mick Guilbert · Oct 6, 2015

Many thanks for all your help, it did turn out to be the relay and I now have a working heater.
I also Sussed the sunroof I think it needs a new seal as it does not close smoothly, it would appear that the seal has swelled or rust has gathered beneath the seal. Something to look at at a later date.
