Quick one guys, my heat and defrost takes a while to heat up, longer than usual, and when im at a stop it tends to cool down a bit until i start movin again, is this simply thermostat?

 

One possibility. Q.: Does engine cool (see gauge) or only cabin??

Most probably a leak, cooling liquid level down, core heater valve vacuum (15.) hose leaking, thermostat, etc.

Leak means also air bubbles.

Seek for leaks, correct, fillup, bleed (Bvalve at 7.), vac hose...




Check for more info:

 

gauge reads normal, i'll check it out tommorow since itll obviousy be snowing again and sucks to work on your car in the snow.. thanks man

 

Have not experienced, but they say bleeding is PITA in maxima. See stickies.

I drive one hour with smtg bleeding in extreme cases to get all air out... Btw. Air might be the only problem.
