Thanks for asking. The car warms up fine, and when driving on the freeway with the EC button chosen and no fan, I get little or no heat no matter the setting. If I turn the car off , then on immediately, I get a decent amount of heat with no fan, but if I turn the blower on, either high or automatic, the heat dissipates quickly. I ran a resistance test on the sensor and it is o.k. and the suction blower now pulls air past it. When I have heat available, if I pull the connector to the monovalve, I get no heat - which I was told is the test for the monovalve's proper operation. Frankly, I am beginning to think I have a problem with the recirculation pump not running, but that is so buried it is almost not worth it to fix the damn thing. Any fis or testing suggestions will be warmly welcomed!
