4wd is electronic; activated by push-button actuator located on dash. I have replaced this once; a couple years ago; problem solved. Put a new one in this time- didn’t work. When I attempt to go from 2wd to either 4hi or 4lo by putting the vehicle in neutral and pressing 4lo button and returning to park while indicator light is blinking and waiting until indicator light stays lit b4 putting vehicle in gear and attempting to drive. Thing is… both 4hi and 4lo indicators stay lit and vehicle ‘winds out’ and seems to have ‘no power’. Returning to 2wd has to be done the same way. Not sure if the problem is the module, the motor, or is there another vacuum actuator somewhere? Central Illinois has been getting quite a bit of snow and 4wd is critical to getting around. Thanks in advance for any insight on this… 4wdriveless<\/p>\n","protected":false},"excerpt":{"rendered":"
