Blower - Radiator Fan - Turn signals quit on 2004 GC Laredo
Hi All - looking for any help/info
Was in a small accident 3 days ago - 2 cars collided and then got pushed into front of my Jeep - no visible damage to my Jeep except some paint and right front fender got pushed in a bit (nothing noticeable), but car that got pushed into me had a significant dent in fender and side panel. I drove home - about 1 mile or so - no problems, temp gauge went up a bit when stopped but figured it was because temps were close to 100 degrees and I was at a stop for a few minutes - came down as I started to drive. Everything seemed fine.
Two days later, as I was driving car - the turn signals quit working, the AC/Heat blower stopped working, and the radiator fan stopped working - so car will overheat if driven ( popped hood and watched for it to turn on - never did). I checked all fuses - nothing blown in interior, checked connection to radiator fan - wires looked good, rewrapped and re-connected. This is way to coincidental that after this accident everything dies - I was wondering if there is anything I can look to pinpoint. I am most likely going thru the driver's insurance company for the repairs so it might be a PIA.
Looked for similar threads but could only find one or two similar.
Sorry if this was addressed in another thread.
Thanks to anyone/everyone who can give me some help.

Think I found the problem. Fuse #20 was blown.
Interior fuse #20 is labeled "IGNITION - RUN" in the owners manual.
Found a schematic on-line that has it labeled -
Ignition Run / Heated seats / A/C Heater control / Flasher - Left and Right turn signal switch sense
That info would come in handy in the owners manual description.

And this was not the main problem.
Could not pinpoint why the fuse kept blowing - so took it to a local shop.
After close to 3 hours with a circuit tester - mechanic found an exposed wire leading to the radiator hi/lo speed fan relay in the fuse box under the hood. Spliced, wrapped, and re-harnessed and so far all has been good.

Having same issue
I'm having an issue like this, radiator fan, turn signals, and blower stopped working. Fan relay replaced and fan works but fuse #20 continuously blows. Where exactly did you find that exposed wire?
