no Heat?

[aperrego]

Any one give me insight on troubleshooting my Heat? Does not work. I know it goes through the water system.

I always check and verify water flow through the heater core first.

Assuming the fan works and blows some air.

On heat the water control valve should allow water to flow through the heater core.

The heater valves on both of my TRs have taken "lazy spells". I'd start there, by feeling the temperature of the hose between the heater valve & the core, if it's not equally warm, manually "help" the heater valve to open.

Can you elaborate? Does the air blow out the vents (blower working fine) but it is cold? Or is nothing blowing out?
