The connection plug pins had some corrosion on them. The cause of problem: bad connection under fuse box going to hazard circuit. I pulled the battery post off, waited 10min, put it back on and this work for a little while until i hit the turn signal and it went right back out. No turn signals, milage, gear indicator, tachometer, speedometer.
Yesterday I went to turn the hazard lights on, soon as i pushed the button the whole instrument cluster went out. HI, I too have a 2002 dodge grand caravan. If that's not the cause, I might disconnect the radio, and check whether I can find anything else on that circuit. Tomorrow I plan to check the driver's window switches, which stick sometimes. My guess, with some help from a friend who is an expert Chrysler mechanic, is that the power cycling is confusing a computer on the accessory circuit, maybe in the radio, and it is transmitting garbage that prevents the instrument panel from knowing what to display. (Actually, it drove fine even when the instruments weren't working, but it's hard to select the right gear and obey the speed limit.) A new relay did not solve the problem. At least we can drive it with the relay out. When I put it back, the problem comes back.

When I remove the relay, the dash board is fine, but the radio and power windows don't work. I checked the fuse box with the ignition off, and the accessory relay was clicking off and on. Wednesday, it wouldn't straighten out when I disconnected the battery, like it had before. My 2006 T&C instruments would sometimes go crazy, then turn off, while the radio seemed to continue making a clicking sound like a relay switching on and off. This should reset most of the codes on your Dodge (just remember that it will also reset the codes on your radio:-)"
You can also try a reset by disconnected the negative battery cable and leave it over for about 1/2 hour. When all fault codes have been displayed, the cluster will display “end” or "E" for end in the odometer display.

If a fault code is present, the cluster will display it in the odometer display. With the ignition switch in the OFF position, depress the TRIP ODOMETER RESET button.Ĭontinue to hold the TRIP ODOMETER RESET button until "Sof" and a number (software version number appears briefly in the odometer window, then release the button. When the key is in the ON position with the engine not running, the MIL will remain illuminated for regulatory purposes. The self diagnostic system displays instrument cluster stored fault codes in the odometer display, sweeps the gauges to the calibration points, and bulb checks the warning indicators. Prior to any test, perform the Self-Diagnostic Test. The instrument clusters are equipped with a self diagnostic test feature to help identify electronic problems.
