Hi, I own a 2005 MK5 Golf 1.9TDI (105) on Saturday it was parked on the path and my dad started it to bring it into the driveway, anyway we were having a look at the heating as it would only work on number 4 (already bought and put in two heater resistors and still wouldn't work) we were advised by a mechanic to have a look at the fan as it may have become clogged. After having a look to no avail we tried to start the car and now it wont run. The car initially starts but immediately cuts out, any suggestions as to what it could be? I've had a look at online forums but can't get anything specific to focus on, also I may add that the dash is completely out, the lights won't come on at all, the headlights, interior lights, radio etc still work though. Already checked fuses and they are all working fine, I'm baffled, any help is greatly appreciated, thanks!
