weird issue with digital dash
 

I have a 1992 lebaron convertible with a digital dash. When I first purchased irt it worked great. Now it works erratically. sometimes all displays on ...sometimes just parts of it. This can be fixed temporarily by clicking the key fob . That is the weird part. Also the locks sometimes just start clicking on their own.The only thing I've done between then and now was to replace the power lock actuator on the passenger side as it had made a very irritating jack hammer sound during activation when I first bought the car. Help!!!I can pretty well jujudge my speed but I do miss the oli pressure and water temp readings.
