The blower motor you have must be for the automatic climate control. If so the fan module is at fault keeping the blower motor on

SOURCE: 1990 olds 98 blower motor

I would start at the fuse. Does the blower motor turn off when the fuse is pulled? A relay is usually used in this circuit and can sometimes "stick" allowing the blower motor to receive constant power. A quick check to see if it is a wiring problem, switch or the relay its self would be to find the blower fan relay and see if there is another one of the value you can swap with it. If the problem goes away, chances are it is the relay but I always like to take a volt/ amp reading to double check my work.

SOURCE: my blower motor stays on after key is off and door is open

hi for the blower motor staying on replace the resistor
check the connector make sure it is not corroded or melted
should have nothing to do with the remote start
this is an after market remote start
then the module could be feeding the blower motor
i have seen the after market modules do some strange things
hope this helps

It might not be a fuse that goes to that it might be a relay thats under your hood in the fuse box. Just a idea for you to try. Hope this works out for you.
