My car starts fine I live in Cape Cod, Mass. and it has no problem starting in the cold, its a 1986 BMW 325es. I get in my car however and there is viruatly no heat, when the car idles its only blowing cool/warm air and when i get going if i turn the fan control knob past 2 it will only blow cool/warm air. However, if i keep it on 2 or below heat will come out its not a lot of heat, or really hot. So does this indicate that its a thermostat, we had the same problam on our 1995 Chevy Suburban and it was the thermostat, was just wondering if it was the same thing. If it is how would i go about replacing it, any help would be nice.

What does the temperature gauge read, if it is not at least halfway between cold and the mid point of the gauge (9:00 O'Clock to 12:00 O'Clock) I say, buy a new thermostat.

if your getting no heat at all then your thermostat is busted because in order to get heat the thermostat needs to be open because the heater core is after the thermostat and if the engine warms up and you get no hot air its cause the thermostat isn't opening due to either lack of coolant or its busted. it also might speraticaly open if it gets too hot and you will get a burst of hot air and then its cold, and your engine will then get really cold and then start to heat back up and do the same process over agian.

Yeah, thermostat. One time I had a stupid mechanic, after replacing my water pump, take off my thermostat and throw it across the room, saying that I dont need it, b/c we're in TEXAS!!! OH, btw, my heater didnt work at all after that dumbass did that. (Its 30 degrees outside here right now
