A/C has been working great,blower, climate control etc,,, then all of a sudden would not come on.... Fuse is not blown, but on the hot side only getting 2 volts?.... this I have done.

1. You can take a jump hot wire go the other side of fuse, a/c, blower, fan speeds everything works?... wire does get a little hot,, short?......
2.Change out fan reg, on inside fender, both controls behind glove box, $5.00 each, junk yard... stilll doing samething.
3.I had to change the key switch months ago, everything was working fine..
4. Check my gas charge everything fine, again if I jump it a hot wire eveything comes on..cold air... alittle hot in in SC...
5. My Question is there another relay somewhere, is it picking up power from key switch, then to a relay, or straight to the a/c. don't understand the very low 3 volts on the hot side,
6. Even pull the fuse box out and check all the wires on #8 to see if everything is tight...... will listen to any and all input .. luckyme
