Question about 2006 Chrysler 300
My temperature gauge is not working at all. When I turn on the car it will just slightly go up and then drop. I already replaced the coolant temperature sensor/sender and it still doesn't work. I borrowed an instrument cluster and it did the same. What else can it be?? Please help, I don't know what else to do. Is there a relay I need to check? Is there more than one temperature sensor/sender?
Chrysler has made major advancements in their technology that is based on 1991 platform, however they still suffer old school problems, if you have an incomplete Ground circuit it will cause odd reactions and rare is the case that 2 identical vehicles will give the same reaction ( dimming in lights on the dash, faulty gauge readings, delayed or extended cranking engine starts, eventually engine control module failure ). Also upgrades such as the stereo or on Board GPS unit and not putting the ground wire back on ( this is the Dash to Chassis Ground circuit that is completed through the antenna thus creating a noise reduction filter by proxy of power flow ). This can even be caused by nothing more than a dirty connection at the battery.

if they arent working i would suspect a loose connection to the computer module or, a problem with the computer try scanning for any codes that there may be

have you got a dimmer switch on your model to dim the dash lights. if you have it may be faulty. link the cables together if the lights work the switch is faulty. if you have not got a dimmer switch
your printed circuit on the back of the dash may be faulty or the plug in the back of the dash is not pushed all the way in. hope this helps

It may not be a bulb, as the instrument cluster usually has a number of bulbs and they probably didn't all blow at once. Pulling instrument clusters can be touchy and may not be for the average "shadetree mechanic" however, typically there are a few screws above the cluster going into the dash pad and a few hidden behind the trim panels below the cluster.

Check you fan test the rad fans on a hot wire from the battery.If it runs with direct connection from battery that means fan is actually working but any of the other fan connecting parts internally are not letting the fan to work.But if fan does not work when you manually test it by connecting it to 12 volt battery then ,yes the fan is faulty and it needs to be replaced.But if fan isa working then the other parts to be checked are
fan relay.Sounds like you need a new fan relay. This relay is NOT in the fuse/relay box under the hood. It is bolted to the radiator support, under the air filter box.
Actually there are many other users facing this same problem Due to faulty fan relay.It was a recall by Chrysler voyager company ,because many of the users face the same problem.But the recall was for the car made in the year 1996.But your problem is same as that.I will mention what company has mentioned in its service bulletin:------
There was a Recall on the fan relay:------
Radiator Fan Motor - Relay Operation
DATE: Oct. 25, 1996
Radiator Fan Relay Operation
1996 - 1997 (NS) Town & Country/Caravan/Voyager
1996 - 1997 (GS) Chrysler Voyager (International Market)
Conditions related to the radiator fan relay may result in the radiator fans not turning "ON" or not turning "OFF" as designed.
The screws that mount the relay to the left front frame rail may break causing the relay to overheat and turn off because it no longer has heat sinking capability to the frame rail. If broken radiator fan relay screws are found, they must be replaced with revised screw P/N 06035202. Also, the relay may have been damaged because of the overheating (but may still be functioning) caused by the lack of heat sinking and should be replaced.
Some vehicles may have an intermittent interference condition between the radiator fan blade(s) and the fan shroud that causes a high current draw that will fail the radiator fan relay. The relay can fail in an open condition preventing the fan motors from running and causing the engine to overheat. The relay can fail in a closed condition causing the radiator fans to continue to run with the ignition switch turned "OFF". If a failed radiator fan relay is found, it must be replaced with revised relay P/N 04886288AA AND screws P/N 06035202. Revised relay P/N 04886288AA has a higher current capacity that is able to handle the extra current draw related to the intermittent radiator fan/shroud interference.
A small number of vehicles may have corrosion develop in the radiator fan relay connector. On vehicles with this condition, the radiator fan relay connector should be replaced using pigtail service package P/N 04897034AA. So as per your problem mentioned i think its a relay for radiator fan,that has to be replaced.The cost of new relay is near to $80.Replace the relay and it will work. On some Chrysler car models the relay is inside the engine bay bolted to front of the engine bay behind the bumper under the main air filter housing.Its fitted with 2 bolts.Just follow the fan wires.it connects to the relay.But if your relay checks out ok and working then,Problem is related to pcm. power train conrol module not sending a "turn me on signal" to the relay. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

all voltages checked ok, then most probably its faulty instrument cluster board
on which gauges are connected. Yes if cluster circuit board looks ok, then also
it can be faulty. Somewhere there is minute short or burn on board then such
check the fuse box. One under hood and other under dash.
each and every fuse and see if all are fine or not.
