I've only owned my S Type for about a year, a little while ago I developed the 'infamous' hot air problem. Blowing hot air regardless of temp setting. I have researched as best I can and see the fix appears to be a replacement head unit and a valve?
But now the heater 'fan' is also making a terrible noise.
I'm guessing that if I simply go into any garage without understanding what is needed I can expect to spend a lot of money on new parts.
Are the problems linked? Will buying a new valve and a 2nd hand head unit fix the issue? Does it sound like I need a full heater unit?
Thanks
