Hello there, a few common faults will cause your turn signal fuse to blow repeatedly on your 2003 Jeep Grand Cherokee. If the blower and turn signal issues started at the same time its very likely there is a short in the wiring harness somewhere. When shorts occur they will blow the fuse as the circuit is getting too much power. A qualified technician such as one from YourMechanic will be able to diagnose your electrical issues and make any repairs required.
