Back Up Lights Problems of Mercury Montego

Parked car at home after dropping daughter off in town car performed normally. Five hours later went out to pick daughter up. Started car and had no speedometer, odometer, tachometer, no cluster panel at all. No lights on panel, a/c would not function and backup lights came on and stayed on. The wrench symbol light came on at this time. I tested the car daily with the same results, until Tuesday, August 11th. I had an appt to take it in to a Ford dealer to have it diagnosed. When I started the car at this time, the cluster panel and a/c were working, the backup lights were off (except when in reverse) and the wrench light was now off. However, now the check engine light was on. Diagnosis at the dealership was that the cluster panel was bad and was sending incorrect codes (p0462 & p2067) causing the check engine light to come on. Since those codes are associated with the powertrain control module it could cause the engine to stall at any time.
