Chris Wilson Posted February 3, 2010 Share Posted February 3, 2010 I admit to being pretty weak on electrics, they neither interest nor are kind to me Have a customers MKIV TT J-Spec auto here, fixed all the issues a nast reverse polarity accident caused save one. I see the heater controls don't work, light up or anything. No blower, no movements of flaps, zilch. Fuses under bonnet and in RH kick panel all removed and tested OK and carefully refitted. TRL speed de limiter / speedo converter is also up the pole. Speedo wavers about and struggles to get over 30 MPH. Any ideas? Customer has got a new TRL box so no worries there. Ta!

JustGav Posted February 3, 2010 Share Posted February 3, 2010 I can dig out the AC wiring diagram if it will help.. I'd hazard a first guess at aircon control as well. Quote Link to comment Share on other sites More sharing options...
