Question about 1995 Cadillac DeVille

1 Answer

My 93 cadillac seville blower motor was staying on .so i disconnected the conector to the motor under the hood. i found that there was battery voltage on connector. then i jumpered the battery to terminal on the blower motor. the blower motor started turning without other terminal being grounded or connected to anything. could this indicate a short in the blower motor somewhere. if i operate the switches inside the car i didn,t get a voltage change of any sort on the blower motor connector. do most blower motors than work off of a current change? i had this problem many years ago and it wouldn,t show any changes to control the motor, voltage wise and we had considered wiring changes, a new switch ,(god bless the old days of a simple make or break contact), or blower motor we finally chose blower and it worked. thaats why i asked about the current control cause in those days they didn,t have such an idea. maybe things are still the same

Caution: Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

Removal Procedure
1. Disconnect the negative battery cable.

2. Remove the camshaft cover.

3. Remove the blower motor.

^ Disconnect connector from the blower motor.

^ Remove the blower motor screws (either 3 or 5 screws).

Installation Procedure
1. If present, remove the 2 ribs located on the barrier. Refer to Step 3 and the illustrations in the Instruction Sheet, P/N 52494110, found in the blower motor kit.

Important: Ensure the blower motor gasket makes a complete seal around the blower motor.

2. Install the new blower motor with heat shield. Refer to Steps 4 and 5 in the Instruction Sheet, P/N 52494110, found in the blower motor kit.

3. Install the blower motor retaining screws.

It is under the hood, look at the center of the firewall, behind the engine. See the round metal object protruding out from the duct? That is the blower motor.
Disconnect the electrical harness, the cooling hose and the retaining
screws then remove the unit
