I have a T reg Astra and a couple of days ago the heater stopped blowing hot air. Its has come back on sporadically but it definately not as warm. Also the temperature gauge doesn't budge even after a good half an hours driving.
After reading some other posts on here, its looks as so I would need a new thermostat. I am a complete novice when it comes to cars, would you agree that a new thermostat is what is needed?
Also, could anyone give me a ball park figure as to what this would cost to fix at a non-vauxhall garage?
Thanks in advance, Andy.
