Puny air conditioner

The A/C now works.

Yesterday I took the car to sc Seattle to get copies of the A/C related repair orders in preparation for submitting a "lemon law" request for arbitration. While I was there, the service manager (BJ) and I spent about a half hour in the car recording interior air temperatures and vent temperatures so he'd have data to discuss with his area manager. During this time, he pulled the duct temp sensor out at one point to see if that would have any effect. It did not so he re-installed it and we shut off the car.

Today, I made a 130 mile round trip to Seattle. On the way over, outside air temps were low enough that I had the heat on. But on the way back it was in the mid-80s all the way. I had the temp control lever set mid-way between 60 and 70 and it never "timed out". I even stopped once for about 10 minutes and the car got pretty hot inside. I didn't change the temp selector and the system automatically went to recirculate and went back to normal when the cabin cooled sufficiently.

I called BJ when I got home and gave him the good news. We don't know why this worked or even if this had been the problem all along. As I reported previously, there were no associated fault codes.

All's well that ends well.

Regards,

Great to hear all worked out. Could it have been a poor conection on the sensor?

That is my only thought.

The sensor is monitored and we had confirmed on a prior visit that it was sending a signal to the HVAC controler. My only idea is that the connector was not "tight" but was on enough to be sending a signal so no fault code was ever set. By moving it around and then plugging it back in the contact was fixed and the sensor was able to communicate correctly with the HVAC.

Again this is all theory but I will take what I can get

One of the reasons I purchased a used 09 Pure is because all the new 09 Passsions and convertibles I drove had lousy AC. I am in Vegas and need my AC. The used Pure AC has been great, new stereo and passion wheels and I am now loving it. Still think about the convertibles, if the las Vegas dealer was not so gready I might consider trading up
