HVAC blower cycling on and off automatically
New to the Jeep Garage, and I'm currently searching for any information relating to the HVAC blower motor continuously cycling on for approx. 50 seconds, then off for approx. 25 seconds when the HVAC system is turned on/running. This does not occur when the system is off.
Bought our 2011 WK2 Grand Cherokee Laredo used, and recently found pieces of the actuator gear on the passenger floor. Actuator and cam/gear on order, glove box and silencer removed.
HVAC was working until this week, checked/charged R134a, it works, driver side A/C & Heat controls work, passenger side controls get no response, so will be fixing that when parts arrive.
I'm not sure if these two issues are related in any way, but I'd like to troubleshoot and diagnose this problem while I've got it taken apart, so any insight or help would be appreciated.
