Question about 2003 Nissan Altima
My vents only blow warm/hot air even when dial is set to cool. Air conditioning seems to be fine however. When I turn the temperature dial it feels like something is being 'flipped' but it is not smooth and there is resistance. It feels like the dial is not shifting whatever it is supposed to be shifting properly. Any suggestions?
Thanks in advance!
I am a nissan master technition in Wichita Ks. we see this problem frequently. there is an air pocket in your heater core, due to low coolant level. for some resion or another your vehical is consuming coolant (usually head gkt leaking into cyl). and sence the heater core is higher than the radiator, the air pocket gets stuck in the heater core.
wait till the vehical is cooled off, remove radiator cap, install coolant funnel (avalible at any auto parts store). lift front of vehical off the ground (to get the radiator higher than the heater core), fill coolant funnel and start engine. allow vehical to reach opperating tempature and the air pocket will work its way loose. you may need to rev engine to change coolant flow rate in atempts to remove air pocket quicker.
sorry about the spelling
