I have a 1995 Dodge Intrepid and when it's warm outside or the car has been running for a while the instrument cluster and eletric fan stop working and when the eletric fan stops working the car over heats. No one I have spoke to has any idea. Could you please help me out.

Re: Instrument cluster stops working when hot
I will take a stab at this. Have you checked to make sure that the fan switch is not bad? Are you stating that the fan works normally, but when your engine gets hot the fan stops?
I would do what I have always done in this situation. Find a hot wire under the hood that is hot when the key is switched on. Run the fan to that wire. Then when the car is on, the fan will work. An electric fan is a pain in the but. They do this a lot. You can buy a new fan motor switch or take my way that I always solve this problem.
I can't remember if that is front wheel drive or not. If there is any way to take the fan off and replace it with a flex fan, you can do that. This will never stop working unless your engine stops working. This works great if you have a rear wheel drive car. I do not know what that car is. Have you checked your thermostat? This could be a sensor going bad. Either way, I would change the thermostat, because if you have never changed it, you will be better of knowing that the thermostat is new.
I do not know if you liked my answer or not. but I explained what I do for this problem. My father was a mechanic for 40 years before his death and I worked in the garage from 8 years up til his death. I do all of my mechanic work if at all possible within my limits. I know for a fact that this way will not let you down unless the fan decides not to work one day. I have not seen that happen yet. I hope that this fixes your problem. Rate this as a fix if you are happy with the answer. If you have more concern or questions, feel free to ask me more. I am here to help any way that I can.

I'd have to check voltage and ground for the instrument cluster. I noticed one of the fuses for your instrument cluster goes hot with the key on, same thing for ac compressor. I'd have to voltage feed to and from ignition switch for applicable fuse. Check the ignition switch wiring connector. I can't rule out ignition switch itself, at the moment.
There could be other issues?
Ignition switch faults are common on some makes and models.
Instrument cluster wiring connector problems. Sometimes if you disconnect and reconnect the instrument cluster connector, it may start working again, also, cycling the instrument cluster connector may reset, if it starts working, well, it's working for now, may quit again.
Some instrument clusters may do a self test, don't know about yours?
Press and hold odometer reset button, turn key to run position release odometer reset button, watch the odometer. Your indicator lamps may turn on and off, the gages may cycle in small increments. The cluster will exit self test on its own.
You may have to check buss circuits.
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.

IF SLAPPING THE DASH WORKS, THE PROBLEM IS MOST LIKLEY A BURNED WIRE CONNECTION IN THE INSTRUMENT PANEL WIRING, YOU WILL HAVE TO REMOVE THE CLUSTER AND DISSAMBLE TO REPAIR BROKEN WIRES IN THE PANEL HARNESS CONNECTOR.
I just experienced this problem. I called my mechanic and he knew what it was because it happened to his wife's Intrepid.
The solder connections on the back of the dash crack allowing it to work at times due to temperture variations. All he did was remove the cluster and re-solder it and replace it. It now works perfectly. He charged me $100. Cheaper than a new cluster!
does the cluster light up when your headlights are switched on? if not then iinput cable behind the cluster may have come loose you will have to take the dash apart to get the instrument panel off and get to the input wire. If it does light up then you may have a loose connection and or a PCM problem which is the cars computer have your obd II codes checked at autozone.
