Airconditioner fan isnt blowing in my 1999 mercury cougar

You may have a bad relay. the relay for the blower motor is located in the fuse panel inside the vehicle and is in the "R14" position (see picture of fuse panel location a nd diagram of layout below). I believe but double check and please don't take my word on it (check numbers on relays to see if they match) but I believe the R13 and R14 are the same kind of relay and IF they are switch them to see if that's the problem. PLEASE double check the numbers I may be wrong. I hope this helps and good luck.
