turn signals and blower motor died
 
ok here is the background on my problem:

2003 Jeep Grand Cherokee 4.0L Engine, Auto Trans, No automatic temp control.

I was driving and I had my A/C on, all the sudden I heard a strange sound coming from the heater vents and my blower motor stopped working and my turn signals died.

This is what I have done so far:

I pulled the blower motor resistor out and saw that it was completely fried, there was a break in the metal as well as some corrosion and cracking, so that is new and replaced now

I pulled out the blower motor and jumped it to the battery, and it works fine.

I have replaced the combination flasher under the dashboard, still no change in my problem

The hazards word fine and there are no fuses blown in the entire Jeep.

Any ideas?

update: I took apart the control panel for the a/c and heat, and i jumped the relay that is located in there. This caused the blower motor to start working. I have a new relay on back order with the dealer, now in the mean time what do I do about my turn signals? they still do not work.

wow, thats crazy. hope you get it fixed. sorry, but I dont have a clue what could be wrong.

My Jeep just did this same thing today when I got off work. Have you been able to fix everything?

mrbigglesworth 10-20-2010 12:14 PM

ok, the new relay came and it still does not work, so the only thing i can think of is that there is no power supply to the relay. I know the blower resistor is good, the blower motor is good, and the entire control panel for the heat/air is good. The only thing left I can think of is the air mixture knob(the hot/cold). Where does this knob go? Is there a mixture door/motor some where that needs to be replaced?

i was having the same problem. My signals and my blower motor went out at the same time. Also fuse 20 (HEVAC) kept blowing. It turned out to be a wire shorting out. The wire was located on the driver side going into the transmission. The insulation on the wire had rubbed off and the bare wires were touching. I cleaned them and put some electrical tape around them and everything started working again.

Wire?
 
Please can you name the exact position of the wire because my jeep has the same problem and I suspect that I have the same wire problem. But I need more details to fix this. Thanks

Hi:
I know this is an old thread but my Grand Cherokee Limited just did the same. I was driving and stopped at gas station, when I put it in park the blower died, the ac control panel died and the turn signals wont work. I checked all fuses, resistor, etc. and still no luck. Any ideas?
Thanks
Steven

It's the #20 fuse under the dash. HEVAC. It is a red 10 AMP.

I have not looked for the wires yet.

I have a 2004 Jeep Grand Cherokee Laredo. My blower fan stopped working and left & right signal. I did find that #20 fuse (10A), under the driver dash, did blow, replaced and it blew again. It was a frayed wire to a sensor in the transmission that made it happen!!! GO FIGURE!!!
If you go under the Jeep, on the driver side, above the Transmission pan there is a sensor with 3 wires going to it. I separated them, cleaned with brake cleaner and used electrical tape to cover the frayed piece (which I will replace with liquid electrical tape).
I attached the pic as someone requested.
