Pull the electrical connector off of the monovalve....this should give you full coolant flow...ie full heat. If nothing happens, unscrew the 4 screws, and pull the valve out - note the order in which the part go into the hole.
Thanks for the reply, Larry... does the electrical connector pull straight up to take it off? Didn't seem to want to pull off easily and I don't want to compound the problem by breaking it off...

I also see that I can purchase a complete assembly or for far less, just the mono valve repair kit, which based posts here, seems to be an easy repair. Do I need a complete assembly, and is it a lot harder to replace, since there are hoses involved?

Thank you,
