my car went into limp mode tonight on the way to my friend's house
i never knew such relatively simple problems could cause so much sadness..
i want my baby back..

still no check engine light, still wont start after hot stop, still showing 121 on the HVAC (almost continuously now)... fans on at highway speeds (not supposed to happen)...
i hope they can narrow down the issue tomorrow. if they can't i'm calling the dealer. fark.
Good luck. Stop driving that thing till you fix it.
on the ride to work this morning my mechanic was 'startled' by the behavior exhibited by the climate control block 49 readouts, he said it wasn't possible for the car to jump around like it was.

if its cold, your heater core is blocked,
3. check you radiator inlet and outlet lines for a huge diference in temp/ feelable pressure by hand, if there is a huge disparity between the pressure and return, radiator has an issue.

select output tests, and go through them all, the after run coolant pump should get activated.
