I need some help,have no heat inside the vehicule. I did install a thermostat but that did not fix the probem. Both radiator hose are hot and one heating core hose is hot.the other stay cold. There as to be a valve that is malfunctining at the heating core but I dó not know how to check that
Any ideas, Nissan want 10 hours to take the dash board out .

It could be a couple things, if the temperature control is vacuum or linkage wire operated, might be a case of hose that has come off, or the little keeper washer fell off holding the wire on. Either way, the temp shutoff valve is not being opened.

Thanks for the info I will check that valve tomorow I believe it vacum operated.
