Ooooookay... well, no one has checked in, but here is an update:
Problem has NOT resurfaced. I'm thinking it was just a fluke of slightly high A/C pressure+high FL heat+low speeds for an extended period of time.
But, an oddity has occurred that I can't imagine is unrelated: Know how when you turn off the car and turn it back on, the A/C always automatically comes on (some folks complained about that)? -- well mine doesn't anymore.
If I leave it off, but fan blowing (vent) turn the car off and then start the car again, it stays off
I'm thinking there must be a specific relay or fuse associated with this... anyone have any ideas?
Also, for those of you who would rather it not come on automatically, well this might be the fix...
