Having problems with your 2003 Jeep Grand Cherokee ?

The fuse for the cooling and heating systems keeps blowing when I use the turn signal I have a 2003 Jeep grand cherokee laredo. they must be on the same circuit. the fuse will only blow when I use both the heater and the turn signal at the same time together. could it be a defective flasher?

Answers :

I have the same problem and am going to trace wires for shorts-what I am reading is 80% of the time its the flasher module. Keep in mind the emergency flashers will work even though the fuse is blown and flasher module may be faulty. Flasher modules run about $70 on average-so be careful you don't roll the dice on the fix and be out $70. Again-if I cant find visible shorts, I'm replacing the flasher module. Check the internet for discussions on this subject-it is a very common problem with the 03s. Let me know if this was your fix if already repaired. Thanks and/or good luck.
