i spent this morning fixing my friend'* '90 cadillac fleetwood. When he shut the car off, the blower motor kept running on high....a problem i've seen on these forums. We took the blower control module out and called the dealership for a new one. Evidently this is such a common problem on cadillacs that the dealer keeps the part on stock, but they ran out this week! just our luck.

Hey we've seen that problem before on the models with ECC.
