Okay its kinda hard to explain. My heater acts up and its works fine w sometimes when am just sitting in my driveway and sometimes it doesnt work at all...... But when am driving down the road it will be fine and then when i go and make a trun it will completly trun off and when i go back to haveing the streering wheel stright again it will be fine and if i make so many number truns it will completly trun off.... and wont trun on for while... does anyone know what would be wrong with it? I replaced switch and that didnt work... any idea would be great thanks....

is it a air flow problem, where the air gets weaker or stronger as you make the turns and such?

i would have to suspect a loose connection somewhere in the car, or the blower motor giving out....i would have to suspect the latter tho

okay thanks so i should look for a loose wire? but couldnt that be anywhere? would it be easier to just take it in and get it checked by a professenal? or is it easy track the wires? because some wires are impossable to follow...

Easy way to tell. when it stops working. Hop out and tap the blower motor casing. If it starts back up. Motor is the issue.

I recently changed mine. Remove the strut bar and the metal bracket on the back of the engine and it flips out and the new one jumps in.

Sure sounds like a bad blower motor. Unless you are really broke, this is not the best item to get from a junkyard. A new motor is around $40, I think, and unless you luck out at the yard and get one that was recently changed, it will fail sooner than a new one. On the other hand, they are very easy to change out.
