Ford A/C blower problems

I have a 1999 Ford Explorer with a 4.0 SOHC engine. It has 136,000 miles on it. My wife was having problems with the turn signals and went to an auto parts store to get a new flasher. They were unsure which fuse it was and changed one that looked like it. Turned out it was the wrong one. While changiong the fuses around the blower motor for the a/c and heat stopped working. I changed out the blower relay. I also changed the resistor assembly. I can get no power to the blower. When I operate the fan switch inside the car, I hear a clicking noise coming from the resistor assy I changed.

Any ideas.

Check carefully to be sure that they put the fuses back in the right spots. Check in the owners manual for the proper location of the fuses.
Also check the power distribution box for a blower fuse. It will be in same box as the blower relay.

Good Luck.

You get no power to the blower- are you getting power to the resistor? If no, are you getting power to the blower switch? If yes replace switch- if no backtrack to power supply.
