Review on Dorman Solutions 604 5155 Heavy Actuator by Jeff Apel

I bought this for my 1995 S10 Blazer. As you may or may not know, you have to remove the entire dash to access this part and then it's still hidden behind/under the large wiring harness. After removing this part and comparing it to the one that came out, I was convinced I had the wrong part. After double checking the part numbers and then looking up the OEM part numbers and looking for photos, all new parts only have 4 pins and the one that came out of the Blazer had 6 pins. The wiring harness in the car only occupies 4 out of 6 pins, but one of them ended up in an empty slot on the new drive. I installed it anyway and put together enough of the dashboard to test it out. Low and it worked. I can only give 4 stars because the packaging doesn't say anything about it. In short, Blazer now has a working temperature door.
