2003 Ford Expedition Q&A
2003 Ford Expedition Question: Why ignition fuse blows when air conditioner runs?
Last year we replaced many ignition fuses. We put the car in the shop & as long as they did not run the air it would not blow, The one time they drove the car & ran the air the fuse would blow. We went all the cool months with no problems. We have not ran the air yet this summer, b/c we are afraid of being stranded. We think there is a connection somehow. Can someone help? - marie183
could be a dead short in wiring or a/c compressor is bad a blowing the fuse. this needs to go get diag by a good mech soon b4 other issues arise - globalhelper
