I put my top down last week and a couple days later I couldn't get it to go back up. When I pressed the up button, nothing happened. It did not flash like the safety cover was out of place. It did not flash like there was something wrong. I tried the valet switch and there was no change.

When I found some times, I went to get my codes read. After techstream was hooked up and I pushed the up button, the top went up. And it went back down without any problems. There were no convertible top error codes.

I did find two mysterious codes that show no listing on ClubLexus, they are B1262 and B1272. Anyone know what they are?

I believe those are for malfunction of servo motors for the hvac system.

Thanks Cole. I appreciate the input. Based on your answer, I googled the code with HVAC.

It looks like the code is when there is a disconnect from the HVAC computer to the Main ECU for more than 10 seconds. http://share.qclt.com/%E4%B8%B0%E7%9...cw/cib1262.pdf

I wonder if it was because I disconnected my car battery to try and reset my convertible top computer or if it was because when they detailed my car, they got the wires all wet when they cleaned the engine/carpets.
