HVAC only off and high

'96 cavalier 2.2 i am just wondering if there is a thermal fuse in a cavalier, or if its just going to be a waste of time looking. And if there is a thermal fuse, where might it be?

sounds like blower resistor to me located on passengers side with two 5.5 mm screws .. they corrode and go open on usually mid circuits

sounds like a blower resistor, it's a pretty common problem, i have the same problem with my 01 sunfire, and i just found some instructions on how to replace it, here's the linkhttp://www.j-body.org/forums/read.php?f=11&i=60323&t=60323
