2011 Toyota Tacoma

I have a problem with my 11 toyota tacoma my a/c would not work when turning the speeds and I change the blower motor and the blower resistor and connector now speed low, medium, and medium hi work but when I put it in hi is like I have it in low the air is very low and the blower motor starts going slow I checked the power and low and hi have the same voltage if anyone can help me out please. Thank you.

 

Are you sure you wired the pigtail corectly?
If that's good then check the connector on the back of the blower switch for burnt pins.

 

There have also been a few reports of the fan speed dial itself taking the high resistance hits.
The whole HVAC system in our trucks is a GM special that came from the GM-Toyota joint venture. Not surprising that earlier GM trucks similar to the Taco also share some of the same HVAC woes. For example, I had to search the GM electrical catalogs to find some terminals and connectors as they were not available from Toy except as complete harness.
