The problem with my fiat punto is my boyfriend put the wrong petrol in the car and as he started to drive the car again it started to jerk and then cut out. So we took it to the local garage where it has been since yesterday afternoon. and they pumped out the wrong petrol and put in the right petrol and also pumped up the tyres. Check if the fan is working with the a/c on after some time. If it's not working check voltage on the fan plug and the relay. There are two relays if I remember correctly. One for the low speed (normal temp / ac on) and one for the high speed. 479. Points. 114. Apr 20, 2012. #3. pntmor said: hello dear FIAT owners, I have a 2007 Grande Punto 1.2 8V.
