I have a 95 xj12 without heat.
I've replaced both engine thermostats. (both were bad)
I've tested the Valve with 12v and can hear it clicking,
I've tested the water pump with 12v and can hear it running.
I've change the pump relay with a known good one.
There are no codes in the climate control system, nor in the ECU.
With the engine running and the coolant up to temp, I'm not seeing
12v at the pump nor at the valve.
With the fan set to max, front window defrost and temp set to HI,
I'm getting COLD air. The hoses to/from the heater core are COLD.
Anyone have any hints at were to start looking??
is there anyway to default the system into a heat on state?
