So it looks like I have an issue.
Happen yesterday slogging through the snow when I went to pick up v-belts for my maintenance guys. It popped on as soon as I hit the warehouse parking lot just as I was parking to pick up supplies.
Part of me says SFW because I do hate my car. I want this car to meet its maker, but I still have at least a central air unit that needs replacing for my home in April. The other part of me says snow probably just tripped a sensor and I wonder what it is.
Curiosity won out and I ordered one of those OBD2 Bluetooth scanners. Will see how this will all shake out.
