I was hoping for some help. I was having the normal flashing light indicator on front axles. I started trouble shooting. The actuator itself is working fine. The freewheel engage switch is new. The vacuum solenoid valves are new. All the vacuum lines are tested and Fine. Solenoid valves are marked blue and yellow. I have even reversed the vacuum lines and the electrical connections and can duplicate my problem in reverse. For some unknown reason the blue solenoid valve is not operating correctly. When I reversed the plugs it does. My question is what controls the electrical signal? I am at a standstill. Thanks in advance.
