SOURCE: 1995 explorer heater/ac blower motor

I would check to see if there is a short on the fan controller switch and the motor. sounds like a crossed wire, especially if it's ignoring your speed selection and running when the key is out. could be near the fuse box under the dash. the cig lighter circuit is live all the time as well as a couple others, it maybe crossing with it. I would pull the fuse panels assem down and check for crosses and shorts.

My blower motor quit working changed blower and now it runs all the time even with key off worked fine before blower went out the fuse had also blown what could cause it to run all the time now

Most would say it is the Blower Motor Resistor or a relay..And possibly the dash heater control knob..However it is running all the time even with key off..This means it is getting power all the time from somewhere..It sounds as if wiring is crossed..Did you have to change wiring plug in connectors..?..

I cant turn the heater off, it runs all the time

Sounds like the blower motor control module has gone bad. You can find the module under the passenger side of the dash next the blower motor. Power is supplied to the module all the time. If the module fails it can turn on the blower regardless of the key position.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Your blower motor relay is probably stuck on. Sometimes you can tap on them and it will turn off but you will have to replace that relay.

Heater airconditioner blower motor runs all the time without ignition switch in run position . runs without the key in the switch. the only way to turn it off is to remove the fuse that powers the blower...

If you haven't fixed this yet, your Blower motor resister module is bad. It is located to the left of the blower motor and mounted in the A/C air box. Just pull the right kick panel down and you will see it.

Hello my friend has a 1995 deville that wont heat. He thought the blower was bad so we put a different on it and wired it to run with the key on. It runs but will not blow air into the car. None of the...

If the blower was working why did you replace it?
Heat is made by the engine, and then it is sent into the heater core and a fan, blower motor, blows heat into the car.
First - check that the coolant level is full. If not add MIXED coolant.
Then drive a few miles for the engine to get hot.

If coolant level is full, the thermostat might be bad, or the heater core might be plugged.
