Aloha,

I have been having some electrical problem lately so I checked all of the fuses, unscrew the fuse box, removed and reinserted all of the relays. Since that my windshield wiper (front and back) and inside air fan do not work???
I rechecked all of the fuses and they are ok. 

Questions:

Could I have damaged the relay? 
Do the wiper and air fan share the same relay?
If so which relay is it?
Before that I repaired another electrical problem that had to do with poor grounding of the head light, could it be another electrical grounding problem?
Any suggestion is greatly appreciated.

Thank you

Marco B.
