sup guys my heat seems to work only sometimes.. when i blast my heat to hot it just blow out cool air?and when i have the heat on max no air comes out i have to manually turn up the fan but still blows out cool air?any of you have this problem before?

 

does your car warm up? or is it running cold? it could be the thermostat stuck open, i've seen it happen to other cars and if stuck open your coolant will always flow and never warm up to the right temp. so not only will you get no hot air but bad gas milage cause your engine will be running a little too rich

 

There could be several things that cause this, but one of the most common things is low coolant level. Top it off and see if that doesn't fix it.

 

ok Lexusnyc do a seach for no heat...there are a few things that can be wrong...... small things from topping off the coolant to larger things like getting a new control valve switch...so you must do some research on your own and then you should find out a solution because 99% of the time someone on here has already had the same problem...
