1993 Chrysler LHS VIN: 2C3HD56F7RH334832.

My LHS has about 64,000, AZ car with 57k when purchased with engine problems. I had the 3.5 rebuilt, warped head, and now runs fairly nice. The heater air doesn't get hot, lukewarm warm at best and it seems to have a bit of humidity in it. It's been flushed both ways with no significant changes. Any ideas?

 

Are you loosing coolant? heat flow should NOT have "humidity" in it. That's a sign of a leaking heater core or hoses loose at the connectors on the engine firewall to it.
Nextt item would be a thermostat.

 

I'm not loosing coolant and the thermostat was just changed when the heads were replaced.
