Speedometer cutting out
 

Sometimes the speedometer oil pressure and temp gate will stop working. I don't know what to check. Just changed out all the battery terminals hoping it was a bad ground but it started acting up again today mid driving. Any ideas ?

I have a 06 mega cab had two instrument clusters replace dodge has major issues with them. Not mention 4 AC compressors evaporator rear main seal 3 radios 2 fan clutches. The only go thing about ram trucks is that 5.9 I only have 106k and know when egts get high while towning and causes the engine temp and tranny temp to go up. I filed a complaint with ram and they replaced the cluster even that it was out of warranty.
