Is your enging running cold? Is your engine coolant low?
est votre moteur en marche à froid? est votre bas du liquide de refroidissement?

I understood your problem the first time. Is you engine coolant low? Without a functioning temperature gauge we can not determine if your thermostat is stuck open.

Where is the location of the heat cold valve??

I had a stuck open thermostat on my 2000 Montana and if I would let it idle long enough or drive in the city/stop and go traffic it would eventually warm up and all of this was easily see able with the temp gauge.
