jeep fan not working

[kirktank]

Fan does not work by itself, only runs if I connect it to the battery, changed coolant sensor, now about to change cooling fan relay, a $90 part WOW, if this does not work any suggestions on what else could be wrong???? Fan worked fine until sat afternoon. Fan won't come on with a/c either?? Help please if any one has an ideas. Thanks

You might try a junk yard first, unless your handy with a multimeter. Might also try cleaning some contacts. good luck
