Heater/fan not working

Post by trappitt » Tue Oct 30, 2007 9:56 pm

My fan in the front heater does not work. I have checked the fuses which look ok. The A/c light and rear fan work when the front switch is on setting 1 but front one does not blow on any setting at the moment.

Please does anyone have any ideas?!?!?

Cheers

Have a look at http://www.igmaynard.co.uk/bongo/forum/ ... hp?t=15511. Similar problem & we found that water had got into the fan causing it to seize up that then blew the resistor pack. All fixable with suitable parts & tools.

hi I had the same problem. the fan was locked solid I got a new fan on ebay (£90). This was not the end to my problems there is a resistor under the bonnet right in the middle on top of the air intake you can see the wires going in to it. You need to take it out & resolder the six tabs three on each side. (Or by a new one about £50) there is a fact sheet for this on this website and it is very good.

hope this helps cheers Pat :

It sounds like as the motor begins to seize/drag extra load is placed onto the resistor in the switch...it seems the two problems go hand in hand :roll: As Missfixit rightly points out,the drain hole under the bonnet needs to be kept clean,these clog up really easily,especially this time of year as the leaves start to fall....
