On a nomal day, im on the F150 Forum for my truck But I figure they cant help an 03 envoy 5.3. the situation is I replaced the rear blendoor actuator because the original broke and created a delay in the system of about 5 mnutes. the new actuator reduced it to about 30 seconds. now however, the rear a/c intermediately blows cold and or hot air. the guys at autozone suggest a new expansion valve but idk for sure since the front blows like the ice age.i did turn the new actuator to fit the gear behind it to look like the old one so im hoping I just might have to unturn it a little. what do y'all think? do I needa replace the expansion valve, turn the actuator or something different.

, haven't been able to check moms air-conditioning issue on the envoy, but I noticed theres still some clicking from the actuator area, I personally think I turned the gear too much when I turned it to match the teeth up.
