Recently returned from long trip, and prior to leaving I disconnected positive cable from battery. Reconnected same and all is well except for blinking lights on climate control panel (AC, rear wipers, fresh/recirc air, etc)
Sometimes lights stop blinking after 20 minutes or so, sometimes they never stop. Heated air comes and goes, regardless of temp settings on both driver & passenger sides.
All fuses are OK. I've disconnected battery cables and "grounded" positive to negative in hopes of "zeroing" system, but problem persists.
Any ideas what I should check next?
Thanks! Doc
