1-Check the blower motor resistor , i sent you the location diagram, it is # *****

if you you stuck on high, usually it is the resistor , if not we have to look into the a/c control module in dash ?

Lets check the blower motor resistor first

Is it located under the dash or under the hood?
Expert:  Chad Farhat replied 5 months ago.

It is located on the passenger side under the glove box

Expert:  Chad Farhat replied 5 months ago.

you have to turn on your back and crwal under the dashboard/glove box with a flash light and look up at the black box & you should find it

it will be held by a 7 mm or 8 mm .have to unscrew those and unplug connector and take it off .
