Do you hear the click of the relay when you press up? If yes, then it's likely the relay or limit switch that is the fault

Yes, I was wondering if it could be a relay too. At this point it sure seems like a bad relay would be the suspect. Nothing happens when either front switch is operated in the up position ... no click, sound or dimming of lights at all. All other switches and windows work properly. I even put all the other windows down and tried the thing where you put the key in the drivers door and hold it in the lock position. All windows go up except the front passenger. I dismantled both front switches and cleaned the switch membranes with contact cleaner and reassembled. No difference. There is a substantial amount of circuitry in the switches. I would bet the relay is integral to one of the front switches.
