Sorry for the delay, I work also on the ambulance and had a call. SO you replaced the proper actuator, so did you do a reset afterwards? Usually all that is required is the system needs to be re-calibrated 3 times to clean the feedback circuit in the actuator off. This is done by removing the battery for 10 seconds. Attach the battery then start the engine for 3 mins. Shut the engine off and then repeat this 2 more times.

OK so if you remove the actuator and move the shaft by hand, do you get full proper heat?
