Transmission problem
1998 GMC Sierra V8 Four Wheel Drive Automatic 90K miles

MY 98 GMC K1500 WON'T ENGAGE INTO 4WD (HI OR LOW). I'VE CHANGED THE FRONT AXLE ACTUATOR AND IT STILL WON'T ENGAGE. THE LIGHTS BLINK ON THE DASH AND I CAN HEAR A CLICKING UNDER THE DASH ONLY FOR A FEW SECONDS AND THEN THE LIGHTS STOP BLINKING. I TRIED CHECKING THE TRANSFER CASE MOTOR(NP1), I'M GETTING POWER ONLY TO ONE OF THE SIX PINS WHEN THE IGNITION IS ON. THE FRONT DRIVE SHAFT SPINS FREELY IN PARK. WHERE DO I GO FROM HERE?

Do you
have the same problem?
Yes
No
