In addition to checking the heater solenoids, you can feel the temperature for the hoses attached to the valve assembly. Are they all cold? Have you checked for an electric auxiliary pump?

An option for airlocked cooling systems is to vacuum bleed with the engine running cold. I'm not talking about 20", just a little vacuum.

Well more drama lololol

So I bought a new heater solenoids and put it in and of course I though I would be able to warm my old Bones but still no good

So it seems it must be an electrical problem

Maybe a heater. Relay?
I see there is one under the hood on the passenger side in the sealed electrical box

I checked all the fuses and they are okay

The other way is just to bypass the electrical and put a positive line directly to the switch to see what happens

But I would like to find the problem

IIRC, the solenoid valves are open when no power is applied, and they work by closing the valves (pulsing) to restrict flow to the core. If this is correct, unplugging the solenoid should simulate full heat.

When you replaced the heater valve, did you check to see if the valve was clear with no restrictions and open? Sounding more like you have a restriction in the heater cores, preventing the flow of coolant.

Review post #9 for flushing the heater core.

Well I'm not sure what happened yet but my heater started working

Last night I pulled apart the old solenoids and they were both seized and not operating

This morning I set off to work and no heat
40 minutes into the drive with blankets pulled over me to keep me warm the heater suddenly started working

So I'm not sure if it was electrical or water blockage so I will flush the core out this weekend to see what that looks like

The good news is it's working and I am thankful for everyone's help and advice

Great. The end result is what counts.
