the heat on my 99 jeep grand cherokee wont blow any air. when driving faster that 45 mph, I can feel warm air coming out of the vents but the blower wont work. I have replaced the fuse under the hood for the blower motor but it didnt work. last winter there was a fuse type box under the glove box that had alot to do with it I think. last winter you have to wiggle the box to get the blower to kick on. any tips you might have on what this box is and how do I replace it?
