No defrost

Posted

Ok guys my wife tells me that her car 2003 Nissan Altima 2.5S wont defrost or heat up unless the car is moving down the street. If she stops at a stop sign or in traffic the car will stop blowing hot air?!?:banghead: Anyone have any great ideas on where to start with this problem?:shrug: Thank you for any and all help!

Plugged up heater core? Vacuum problems? Some vehicles operated the heater valve (coolant control) with vacuum so check to be sure the vacuum line are good.

I googled it & came up with air blocking the heater core... at RPM the water gets forced by it. There is TSB on bleeding the air: http://www.justanswer.com/car/12e0j-i-m-having-problem-2003-nissan-altima-heat.html It might well be the radiator cap return gasket is shot so it is drawing air allowing this to happen. I went nuts with dear daughter's Pontiac Sunbird that had a system that had to be purged.
