FYI:
Called Jeep yesterday (Tuesday evening), They can have a look on Friday. I said I needed a courtesy car - they said 2 weeks wait. I kicked off. 5 week old car, already the 2nd time its been in 1st for gear box, now for this, car is dangerous with no de-mist capability etc etc. told them I would drive a sales reps car while they fix it.
30 minutes later they called me back - they had a very coincidental cancellation, meaning there was a space in the work shop and a car available for first thing this morning...
Anyhow, turned up there at 7:30 this morning, noticed VIP stamped on the paperwork. Mechanic was straight in it, under the dash and glove box. 10 minutes later it was fixed. Dodgy connection on the blower controller under the glove box. Apparently "a passenger could have knocked it off". Well that's a crap place to put it then if you ask me.....
My experience with the dealer has been good so far, but I'm not impressed with things going wrong this early in the cars life. I guess I just need to see how it goes.
