Cadillac Repair: Battery drain, battrey, ligths

Question
1993 eldoroado. when I turn the key off the dash panel ligths and the heater blower fan will turn on after I get out of car and drain the battrey.

Answer
What mechanical work or ANY kind of work has been performed on the vehicle recently ?. As most problems that occur after a recent repair was made can be traced back to the area of where the repair was made as a wire connection came loose, Look around in the area where work was performed.

The most common fault when the blower motor continues to run after the ignition switch is turned OFF is a typical fault within the BLOWER MOTOR POWER MODULE of which will require replacement.

This is the most common BUT tets should be perfromed before any component is replaced.
