no heat - brrrrrrrrr

My 93 Villager's heat stopped working. I checked the radiator, fluid was low. Found a leaky hose. Fixed that. Still no heat. Any ideas?

check heater hoses, check water pump

i would have to assume water pump was working or engine would overheat. Hence logically, one has to see if hot water is flowing thru heater core. This leads to one of two things: either the core is clogged or the switch that opens the valve is stuck shut. I would find a way to bypass the switch so that the valve is fully open then disconnect the two hoses and try to shoot a garden hose thru one of them and see if any thing shoots out the other. If it does, then switch is bad. If valve wont open no matter what, then valve is faulty. I have not gone looking for the heater hoses on my 94 so i am not sure how accessible they are.

one word: thermostat

You may just have air in the system.....when you replced missing coolant did you follow procedure to fill it with coolant? There's a specific procedure to follow; reason being that the heater core is quite high compared to the hoses and cooling system hence leading to air in the system.......
