If your amp is bad the servo could be fine. The amp is what supplies the power to move the servo to it's requested position. Remove the servo cap and change the temp settings and listen and watch to see & hear it run. The temp guage in the dash, the temp control work together to bias the amp to move the servo to the correct position. The servo turns the hot water on and off and routes the vacuum to the correct pods.
Timing has a lot to do with the outcome of a Rain dance.
