Hello to all i hope someone can help me im freezing in the mornings,my heater doesnt seem to heat up,i put in on 32 and it takes forever to just get nearly warm but not even warm,i might drive my car for around a hour or more to just get the feel of kind of warm air.And when i turn my ignition on to start the car the panel flashes a few times.Not long ago i had changed the thermostat my mechanic said to put 1 with a double cilynder or something like that anyway i did and for around 3 weeks it work perfect i was getting so hot that i had to put it low and put the temp lower,now its back to under warm.Any one had the same problem????? need help please,thank you in advance to everyone who gives me a advice on it.Should i change the heater tap??? and put a new thermostat on it again????
