Heater broken, any ideas?

(1/3) > >>

Garth:
Right then, after me messing about with stuff yet again, the heater on the golf has packed in. The fan still works as it should and the temperature can be adjusted, but it only blows out freezing air at your feet.

I dismantled half the dash and have worked out that the blower itself is working fine, but the flaps that move the air to the different vents isn't working. Pressing teh different buttons on the climate controls does nothing, I cannot direct air anywhere but at my feet. The re-circulation isn't working either.

This is very odd. I have checked all fuses and they are fine, I have disconnected everything and re-assembled... twice. I have checked all connections and then disconnected the battery and re-connected with no change.

Is this perhaps something that could be checked and sorted with VAG-COM or will it be a new blower assembly?
Any sage-like advice would be grewatly appreciated!

VCDS may point you in the right direction with a fault code.  If you wanted to go more in depth you can also use it to carry out functional checks.

When you say 'messing about', what exactly were you doing and where?

just the usual stuff, taking the control panel out to mess with it, then testing supply cable voltages with a multi meter.can't see how i've done damage, only thing i can think of is that i somehow short circuited it. If that was the case. I would expect a blown fuse.

Yeah I guess everyone does that  :signLOL:

Have you confirmed that the control panel is properly plugged back in?

I guess a VCDS scan would be the next best idea, should point you in a bit better direction.

Surely everyong takes the control panel out at least ONCE a month to change LEDS's don't they?  :confused:
Or is it just me??  :grin:

Yeah, checked all connections and even tried my spare control panel, no joy  :sad1:

I guess I will be asking Darren to come round again this weekend  :happy2:
Thanks
