i have this 1992 mpv 3.0L rear wheel drive. i have no heat at the front. i thought may be it's just thermostat so i did change it and i also flushed my cooling system as well but when i tried it my fan just blowing cold air. no problem at the back heater it gives out heat. what coul it be the problem and where can i buy the parts. i live in surrey, british columbia, canada. any advice is appreciated. thanks

 

Hi. Yeah, have the same problem with my '91. Found out that the heater is not connected to the rest of the cooling system! The back heater is, though. Problem is, now I need a diagram is reconnect the thing!!! Does anyone have an idea where I can find such a diagram?
Cheers.
