Just a quick question, my 97 GXE's blower motor chatters and I don't think that it is blowing enough when on recirculate. The fan speeds up just a little when switching from fresh to recirculate but it doesn't make a big differance like in all my past autos. Wondering if anybody else has chattering problems or a weak girly man blower. Don't get me wrong, it still has quite a stream of air when it is cranked to 4 but I dont notice a differance when I switch back and forth. Thank you and call again.
