Your best bet is to go to a salvage yard. the cost for a new one is quite pricey. you will save a whole lot of money trust me on this. if you can't find one at a yard buy one through Napa or Oreillys cuz if you go to a dealer your gonna pay an arm and a leg for it.. please rate .......thanks

Car is saying it is hot when its not

Could be a problem with ect--wiring circuit--instrument cluster. I'd have to double check your temp gage by using an infra-red temp gun on your engine.
I can't say replacing the ect will help anything? The location is circle with a c in the picture, note the vin.

Instrument cluster black

If you have the 3-Panel Digital Cluster, with the Fuel on the Left.., Speed in Center.., and Odometer on the Right.., and the Cluster is going Wacky.., works one minute then craps out the next.., take the dash apart and remove the Digital Cluster. Take your time when unplugging the harness behind the cluster, use a mirror if you have to.., to unplug it correctly.

The problem with this Digital Display is the Solder Connections.., at the 14-Pin IC Chip.., which is directly behind the Odometer Display on the main Circuit Board. When you get the Cluster removed.., again.., take your time.., and take the cluster apart.., so you get the main circuit board out. The 14-Pin Integrated Circuit (IC) Chip is marked with an IC2 on the main board.., which as mentioned is behind the Odometer Display. The IC Chip is usually Black in Color.., and is '@' 1/4" x 3/4" You will need a Soldering Iron.., @ a 30 watt with a pointed tip.., don't use a Soldering 'Gun'., too hard to use and too hot.., you don't want to cause yourself more problems by messing up the board circuit tracks by overheating them.., so it's best to use a smaller iron. It is a good idea to have some fine strand solder on hand.., but you should not need it.., all you want to do.., is to 'Re-Tin'.., or 'briefly' melt the Solder at all 14-pins of the IC Chip.., on the back side of the board.., to Re-Flow or Re-Solder the Connections of that 14-Pin IC Chip to the Circuit Board. That's all it is..!!!

I just repaired my 1991 Olds Cutlass Supreme 3.1.., 3-Panel Digital Instrument Cluster in this manner.., and it has been "Perfect" for a month now..!!

Take your time.., get it all back together.., and my bet is that it will be good to go for many more years to come..!!

Good Luck.

2005 Dodge Caravan instrument cluster and blinkers stopped working along with the seatbelt and door chimes

many things run through the cluster including remotes and door locks. If its like like most dodge electronics, you'll have to do some dissection. remove any trim and bezels from around the cluster. remove the cluster and set on a bath towel clear side down disassemble cluster to get at circuit board. take a heat gun(not a blow drier, they dont get hot enough. Heat only the board, moving quickly to avoid hot-spots for three to five minutes a side. this may warm up the solder enough to make better connections. This has no guarantee that it will work. You still may have to have someone with a soldering iron rework the solder points.

2003 Jetta Tdi instrumentation cluster both LCD segments are no longer displayed Remove cluster and disassembled carefully removed displays and cleaned contact pads on circuit board and cleaned zebra...

Your LCD display is out of order. You can try to find one new on eBay. Chinese brand is cheaper, but VDO is better. After buying the LCD display you will need to install it.
See this link as an example of a new LCD display installation in the instrument cluster.

2000 jeep grand cherokee gauge cluster is working off & on where do i start with troubleshooting?

If it's just the Temp/ Fuel gauge,,, my money is on the instrument voltage regulator. (it governs the voltage to these gauges regardless of the incline (up/down for the fuel gauge) or the battery voltage 12.5 - 13.8 . Other than these it may be an earth connection problen (long shot) because the instrument panel relies on many many signal imputs. !

How do i replace the check engine light on a 93 saturn sl automatic a mail

If you are looking for how to change the bulb itself you must first pull out the instrument cluster. Be very mindful not to damage any of the wiring harness you will encounter in this process or the flexible circuit board on the back of the cluster itself. Once the cluster is out look at it's backside.You will see the flexible circuit board held in by some screws and 24 plastic nubs. These nubs are the sockets of light bulbs. The one for the check engine light is one of the 13 that are all in a line at the bottom of the cluster. If you look at the circuit board you will see that they are labeled as to what they do, but for posterity's sake the check engine bulb is the third one in from the right. Hopefully for you the base will still be there (they can kind of be a pain to find). For the bulb you can use size 73, 74, t5... The original, if memory serves, was a 74. But honestly any of those will work.

Entire instrument cluster in my 97 plymouth voyager not working

To fix the dash going out try this. This is a common problem with the voyager,caravans and Town & Countrys. What the problem is is a cold soder in the interment cluster itself. The problem area is where the plug comes from the van into the cluster. You need to take the circuit board out of the cluster and reheat the soder on the back side of the circuit board were the plug plugs into. This will fix the cold soder permanitly I think its about 16 pins you have to reheat with the soder gun. If you don't feel comfrotable doing that you can just replace the interment cluster and it will be fine but if you buy a used one make sure it was tested. This also may fix the ABS light and the airbag light. Hope this helps I have done several of them.

Odometer light out on a 01 buick century

I had this same problem and I removed the long plastic dash piece that goes from door to door (after removing other pieces which hold that one in place) and then tilt the steering wheel to the lowest position. turn the key and put the car in gear 1 then shut the car off -this enables you to remove the instrument cluster, which is held in by 4 screws. Unclip the back of the instrument cluster and remove the circuit board. On the board to the right of the speedometer are 4 resistors which look like tiny black cylinders -these need to be replaced (if they haven't already fallen off the circuit board). I was missing two and I just touched the other two with my finger and they fell off. I soldered onto the board 150 ohm, 1/8 watt resistors ($1.99 for a packof 5 at Radio Shack). This entire process took me about 30 minutes. I put everything back together in the reverse order I took it apart and my instrument cluster, odometer and gear-shift indicator works fine.
