blower motor switch get hot and smoke

i have a 91 chevrolet astro van and everytime i turn on my blower motor it gets hot and smoke at the switch. i have changed the blower motor and changed the switch before that. i can't figure out what is going on. If someone has a answer please share it with me.

Make sure you have a good blower motor ground and check the blower motor resistor.

I agree. Also, how is the connector? They get burned over time.

Think on that particular model it is under hood by blower motor. Probably in the fiber glass vent housing, on top. Should be a couple wires going to it, easy to see and change.

Agree with Darrell. Call up any GM dealer's parts counter and they'll tell you in two seconds.
