Blower stays on when key off 1998 olds lss

Do you have manual or automatic climate control ? If automatic could be a bad blower motor control module .
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Disconnect the negative battery cable. Remove the rear engine sight shield. Disconnect the positive booster cable from the multi-use relay center. Move the underhood fuse block out of the way. Disconnect the electrical connectors from the blower control module. Remove the blower control module from the blower module.

    Blower motor not working

    If you have an owners manual look for the fuse for the blower. If the fuse is good then its 1 of 2 things. The blower motor or the climate control blower switch.

    The Digital Climate controls use a switch controller which is under the hood and behind the engine. On my 2002 Mercury, the switch was behind the heater line from the intake manifold. The outside of the switch has 2 screws and 1 electric plug and is sticking out of the ductwork by the firewall. The part is about the size of a cigarette package with most of it hidden.

    You may be able to get the 2 screws and electric harness off without removing the heater hose, but before I could get mine to clear the ductwork I had to pull off the heater hose from the manifold. You CAN check the new part as soon as you get the electric connector off the old part WITHOUT removing the old part, hose or screws. Just plug in the NEW and turn on the ignition with the blower ON and the fan should work.

    If that fails its the blower motor.
