I just went for a drive and realized my Boost Guage is not working and stuck next to zero. It was always working and suddenley today stuck!!! Im taking the car into Ford Dealer to get defective headlights changed on warranty(I hope) as they just got them in. Ill have them look at it and give me an estimate anyways but may need a guage soon. Is there a quck and easy way to disconnect and connect and check it myself? It seems like it is just stuck and does not move even when the car is off.
