a/c fan speed fluctuation issue
yes, i searched. 
89 xj, 4.0, auto, red
when im cruising around town, 45-50mph, my a/c fan speed blows consistently. each speed blows properly. when i get on the freeway, the fan fluctuates. switch is on high but the blower will slow down for a minute, then speed up, etc. over and over till i exit freeway and slow down. it does the same thing in the winter with the heater on. it doesn't matter whether it's on recirculate, fresh or bi-level or what fan speed it's on.
is this the blower motor resistor?
thanks
