So, as I started the car this morning to drive to a local AutoZone to have the codes pulled, the light goes OFF! What? No SES light today Guess because it's Friday!
. Nonetheless, I pulled the codes and will attach a pdf with the printout. I'm curious about the HVAC operation because when I adjust the temperature I do not get any noticable change, which one of the codes seems to support. Any thoughts on these?
I'm still baffled by the disappearance of the light. . .I thought when they threw a code the light remained on until manually cleared by a reader. . .
I also found a significant amount of debris/dirt/bugs in the air filter box, vacuumed it out and banged out the air filter while I await a new K&N to be delivered. I can't imagine this is the cause of the SES but I'm sure cleaning the area didn't hurt.
