Guys I'm working on a 1994 Lincoln town car that went from great heat to no heat in one day. I found the waterpump to be leaking so I changed that as well as the thermostat and that did not cure the problem. My next idea was to change the heater control valve. Alldata has it listed as thermal blower lockout. The picture shows it to be next to the passenger side valve cover, but I cannot find it anywhere on the car. Any ideas? Or anything else I should check to see as to why it has no heat. I wanted to try the valve before leaning toward it being the blend door actuator which seems common to go bad on these. Thanks for any help.

If the fan blows fine, it sounds more like the blend door.

That's Auto climate control. No heat, or is the system not kicking on at all?

No heat. Just cold air coming out.

Yep- then the blend door... or a plugged heater core.

I had that problem with my 1995 Town Car...but it was the thermostat...

I changed the thermostat and it didn't help. Both heater hoses are hot when you touch them so the heater core doesn't appear to be clogged. I guess I will be fixing the blend door
