Question about 2005 Chrysler Town & Country

4 Answers

Lights flickering, gauges going wild, radio resets, ac loses powe

2005 town and country
headlights flicker as well as the cluster panel lights, all lights flicker the radio resets and i can hear the ac loose blowing power. I have had it back to the dealer 6 times and they finally told me that chyrsler said that it just does that sometimes. The problem seems to be getting worse because before just the headlights and clusterpanel lights would flicker then the gauges started jumping and now the radio is resetting and the a/c looses power. when i see the lights start flickering i can wiggle the power window switch and it makes the gauges jump and the radio reset.

    The dealer replaced the headlight switch and it fixed it for a week. they also told me that they searched all the wires for cuts and kinks now right before the radio resets and the ac blower cuts down the van bogged down and wouldnt go. only lasted a few seconds but is that something that would be fixed by fixing contacts on bulbs everything electrical in the van is freaking out.

    I have noticed that sometimes it takes a little while for it to start acting up. and if i wiggle the power window switch it makes EVERYTHING start flickering and jumping but then it will stop for maybe a minute or three.

There Must be One of the MAIN POWER LEADS that Run Cabin ELECTRICAL. OR ALSO CHECK ALL TRANSITION GROUNDS Such as Battery to BODT ENGINE to BODY Gorunds. This Seems to be A POOR CONNECTION @ A Ground or POWER Point.

The problem you are experiencing is indicative of a ground loop to the BCM (Body Control Module) where everything you are mentioning is controlled.
Wiggling the switch means the problem lies in the wiring or the switch.
Checking the switch & wires will require removing the door panel.
Since the MASTER switch controls all the other doors and windows - the problem can be in any of them.
Disconnect the MASTER switch, and see if the problem goes away....
If it does go away - do the same to all the other doors and windows (unplug them) plug back in the master switch, and one at a time - plug them back in and re-test to see if the problem comes back. This will narrow down the culprit.

Thanks for using FixYa!!
:D

This problem is often caused by the CTM (central timer module) module, the dealer dealer should know this.

Hi,
NOTE: DO NOT REPLACE HEADLAMP SWITCH BECAUSE PART REPLACEMENT
WILL NOT CORRECT THIS CONDITION.
1. Open hood and disconnect the negative battery cable.
2. Remove the instrument panel left end cap.
3. Remove steering column shroud cover.
4. Tilt the steering column down into the lowest position.
5. Remove one screw (Limited/300M) to cluster bezel.
6. Remove the items to expose bezel mounting screws. Items vary depending on model.
7. Remove two screws over upper cluster bezel in instrument panel brow area and all
remaining attaching screws (four on Intrepid, Limited, and 300M, and five on Concorde).
8. Using a trim stick (special tool #C-4755), gently pry out on the
instrument panel cluster bezel.
9. Disconnect and connect the wire harness from the headlamp switch
three (3) times to clean the contacts.

10. Disconnect the wire harness from the headlamp switch and apply Mopar Dielectric
Grease, p/n J8126688, to the harness connector terminals.
11. Reconnect the harness to the headlamp switch.
12. Reassemble the instrument panel.
13. Connect the negative battery cable and set the clock to the correct time.



if that does nto work or u dont have auto headlights then replace the headlight switch.
For the cluster lights:
Its the bulbs! I had this problem!

The contact points on the bulb to the instrument panel is bad, so all you have to do is get the cluster off and unscrew the bulb then bend the tabs on the bulb (contact points) so it can get a better contact with the instrument panel eletrical board.

What I am trying to say is basically your bulbs are LOOSE, causing it to turn on when contact and off when loose. With factors of vibration from the car it can cause a flickering effect.
A/c and radio getting reset will go automatically.
Basically my theory is that power was being interrupted to the radio and the Yellow wire was not holding the 12V. Adding the cap across the 12V and gnd (black wire) adds a small amount to stored power if that voltage drops. Normally the radio would reset itself during the initial crank of the key .
Thanks for contacting Fixya

Sounds like a BCM - body control module (computer ) problem ! Do you know what that is ? Did your Mechanic check for DTC'S - diagnostic trouble codes ? The headlamp switch is a input to the BCM , the BCM is hooked to a serial data network ! The BCM sends a message on the data bus to the intelligent power module which turns on the headlamps . The same with the insturment cluster , has a processor inside . Could be a loose ground etc.... I would try another mechanic . One you knows about computer networking .
