tony1210 Posted May 20, 2008 Share Posted May 20, 2008 hi hope someone can help and maybe save me some money, i have a 03 1.8tdci ghia, i seem to have a intermitent fault with my digital heater control, sometimes when i use the car the digital controls dont work, the display is blank and the buttons do nothing, but the heater fan is blowing on full , with no way of turning it down or off , the next time i use the car everything is fine? its seems pot luck if it works or not. ive checked the fuses and fiddled with the relays but still got the problem , could i be looking at a new aircon heater digital display unit? or am i missing something obvious? ive had the unit out but could find no loose wires or loose connections. i would be gratefull for any help or advice....thanks Quote Link to comment Share on other sites More sharing options...
Steve Posted May 22, 2008 Share Posted May 22, 2008 sounds like the circuit board is faulty..could be a dry joint... if you have to replace it then i suggest taking it out then trying to open up where the connections are and giving a a good going over with a contact cleaner from Maplins. May i ask does the weather affect it? when its hot it works or vice versa? Quote Link to comment Share on other sites More sharing options...
