well, time to take out the inner box and replace the core today...I think I'm having a big brain fart...but I peered under the dash and can't recall the mounting situation....no bolts visable from the inside...h$ll, I only put the car together 2 yrs ago...
Surely I don't have to unbolt the fan box under the hood????
Must have been that 2 bottles of Shiraz I had last nite....
