Heaters

[redeye83]

Hi all my heaters are pretty shit as hardly produce any hot air. What is the best place to start for fixing it, is it the blower motor?

If the fan still works then id probably say heater matrix - used to have these go all the time

Where abouts is it and where best to get one from?

Inside the dash, they're readily available from most auto factors & iirc cliolord made a guide on how to do it

Try flushing the cooling system first.

I've not long done a top end rebuild and have flushed the system. You got a spare one at all mat?

They are only about £30 new so not worth using a 2nd hand one.

You don't need to remove the dash to fit them too, you can slide it forward just enough to slide the matrix out from the passenger footwell side

You sneaky bastard!!!

Couple of things..if the thermostat is buggered would it not effect heating in the cabin? have you replaced it?

The other, try sticking a pressure washer hose into the matrix from the bulkhead. This will certainly clear out any blockage in the matrix. Leave it run for 10 minutes each pipe and make sure you allow the system to bleed correctly thereafter.
If the matrix is not leaking in the cabin can't see why you would want to go through the hassle of replacing it.
