No heat in my 87 300E

Gotta 87 300E, running great otherwise.
Just recently it started to flicker with the heat starting up. It would flicker and intermittently turn on and sometimes stay off.
Just recently the pattern has been that the heat won't turn on until the engine has reached fully warm and stayed there for a couple minutes for the heat initiates. It usually would kick in once the engine temp sensor came up off 40.
Is it the monovalve?
I'm anticipating a bad temp sensore somewhere?
I was thinking a short but it doesn't flicker anymore...
Fuses are all new and working.
Any suggestions are greatly appreciated.
Thanks guys.
Cam
