Hi,
i have a mk1 punto and the heaters have just started playing up, they would not blow out any hot air after approx half hour of driving then all of a sudden they blew out warm air but not hot, then they went cold again. I have not been out in it since but have checked the coolant level which seems to be ok. i started the car and left it running for about 15 minutes and the heaters were still blowing out cold air.
Any ideas please.
