Hi all, i've just bought myself a W plate Escort Td for my daily runner and I think there's a problem with the heater/ac, it was cold all day yesterday and I put the heater on high and the thing would only blow luke warm, I thought maybe it would take a while to warm up with it been diesel

but after an hour it was still blowing the same luke warm air and not really warming inside the car up, any ideas?
Also on the hot few days we've had i've put the air con on and that doesn't seem to blow as cold as I imagined but I just thought maybe it wasn't as good as the air con in my old car? Maybe the two are linked?
Hope someone can help,
Chris
Oh yeah one last thing, has anyone owned one of these before and what sort of milege did you get from a full tank of fuel?
