Intermittent fan for ac and heater. On for 4 seconds. Off for 2 seconds. Also, ambient lighting in car intermittent and exterior temp gauge intermittent. Temp gauge usually shows 55 degrees and when it's in the mood, it flashes the external temp just to tease me. All three problems happened at same time.

Blower runs on an intermittent basis, does not matter A/C/heat. This problem has occurred several times over the past 18 months, it has been returned to the Lincoln dealer on multiple occasions without a good fix. Multiple components have been changed, still no fix has been found. It was returned for the same problem for the 9th time this am.
