HI all
i am having problems with my heat in my 1985 126 380se with about 200000 miles on it, i get nothing but cold air, i replaced the monovalve and it did nothing, i am think i have a stuck thermostat (the engine cools down a little after you start to drive), but before i throw parts at it is there a test to see if its stuck open? i was thinking to start it up and see if i could feel coolant run thru the hose. Also what all controls the heat? my heat is not even luke warm
help its cold here
thanks
kenny
