that sounds like a bad connection at the blower motor

Does the blower work on High when connected properly?
Blower resistors can go bad without looking "burnt"....

Blower Resistor pack going bad or motor bearings seizing .

check your relays but most likily is the blower motor itself

i would replace the blower motor relay .sounds like its stuck in the closed postion, normanlly it in the open . if you have a owner manual go to the index and look at relays ,locate relay pull it out and if it stops the blower with the key off its probally your problem..

Sounds like blower motor is going bad. Get it replaced.

sounds to me like you have a resistance switch problem. The old cars had springs, i. e. resistors to control the speed of the motor. newer vehicles have electronic controlers, they can be very sensitive to corosion. first check the plug the replace the switch.

something has fallen down threw the defrost vent and is stuck in the vent doors or a vent door is not seating well maybe because it is warped

Hello,

The blower motor, as you have probably seen, is under the dash on the passengers side. While in Park with the parking brake applied:

Turn the Key On with fan blower set to High. Locate the blower motor and wiggle the electrical connector. If this brings the blower motor to life, a new blower motor is needed. This, if applicable, is a common failure that matches your symptoms. The new blower is simple to replace, although it is never fun working under the dash.

If you have a 12 volt test light or DVOM (multimeter) you can check for power at the electrical connector. You should have battery voltage (12+) with the blower set on high. Always use a known good ground when testing for power. If you have power (key on, set to high) and no blower operation the blower motor needs replacing.

The resistor you replaced is a very common failure on these.

Give me an update.
