I bought a 2007 Pacifica recently with 15k miles on it. Over the past 2 weeks the horn has started going off unexpectedly while driving or when the car is turned off sitting in the driveway. Sometimes it lasts for 20-30 seconds. Yesterday it went off 9 times while driving. The dealership told me they could not find anything wrong (of course it didn't go off when the car was at the dealer). Has anyone had this problem? Overall were very happy with the car but I'm concerned that the problem is electrical and this is only the beginning.

| Went out to the pacifica the other morn...found the radio playing, a/c blower blowing, trouble lites glowing, all like the key was on b4 start. The key was in my pocket with the switch off. Tried to start (still had a little battery), started for 2-3 seconds and quit, did the same 2 more times after charging battery. Any ideas would be appreciated | |
I have a 2005 3.8L Pacifica bought new in July '05 (out of warranty) with only 27k miles. I've had a remote lock and instrument cluster failure twice now a few months apart. They way I notice it is when I go to remote lock my vehicle I don't get the horn and light confirmation. I get back in the vehicle and power it on and the instrument cluster is dark, no illumination or display. The vehicle still starts (luckily) and everything else seems to work fine. After it sits for awhile, the instrument cluster comes back on and everything appears to work fine again. The last time this happened the check engine light illuminated so I finally got some fault codes to troubleshoot this problem. I did the 'on acc on acc on' trick to get the fault codes to pop up on the odometer. I got two fault codes u110c (No Fuel Level Bus Message) and u0140 (Lost Communication With Body Control Module). Has anyone else experienced this glitch? Anyone know the possible cause, solution? Since my vehicle is out of warranty, I don't want to waste an expensive service fee to troubleshoot this intermittent problem. I can't seem to find a TSB or Recall that specifically addresses this problem. Thanks for any help.

Replying to: cariadlawn (Jun 03, 2008 2:42 pm) When my seats stop working, I pull the fuse for about 10 minutes and then replace the fuse. The seat movement function is restored. I've also disabled the selection for the memory. My hunch is that the memory function is sending a signal through the control module to one of the motors which then are at the extreme, and do not cut off. This in turn causes the circuit breaker to overheat and "pop" which then cannot reset because it remains overheated. We need to post this complaint on the NHTSA website under the vehicle complaints. (If this continues to be a problem for me, instead of paying the outrageous dealer labor charges and parts costs, I will wire (14 gauge wire) a fused circuit from the battery to the door switches and cut out the entire circuit as designed.) |
