Gm part no: 52487131 is what I need but video is not real clear if I need two on the actuator near gas peddle (see below photo) . I can see that one that is broke (not on below photo) on my used 95 K1500 and one that is intact. However, former owner may have been just lazy and left broken one on the same fastener (or maybe parts fell of and accidently fell on ground) . If anyone has replaced these parts and there is supposed to be two of them, or only one, please respond. It is not clear on the below photo if there are two of these parts. Thx

 

Some climate control boxes come with three actuators.
