a couple weeks ago the bearing on the end of my ac compressor locked up and was ruining the belt when i tried to use the ac so i pulled a relay out (until i got the new pulley to run the ac) that controlled the ac compressor clutch along with the cruise control, temperature **** and reverse lights. but then i found a fuse that just controlled the ac clutch so i pulled it instead and put the relay back in. but ever since i pulled the relay out, all of the other things that it also controlled stopped working. my dad has an 03 f150 and i tried using his relay but it still did nothing. i also used my relay in his truck and my relay worked in his truck. so i know the relay is not bad. just wondering if anyone has any clue what could be wrong? it is a 99 f150 4wd with the 4.6 motor
