Question
yesterday my dash went dead on my 2002 sls caddy. nothing worked speed o ,fuel gage nothing half hour later all went back on . now today nothing works again what do i do

Answer
Hello,

Without being at the car, it is impossible for me to diagnose.Intermittent makes all this worse.

It could be a cracked circuit board in the dash unit. It could be a loose ground under the dash. It could be a bad connection at the bulkhead on the firewall.

If weather related, it is a cracked circuit board in the dash unit most likely.
