MadDog Salvaje Posted February 27, 2018 Share Posted February 27, 2018 I have replace the manifold under dash because I thought it might be that it was leaking really bad. Checked all sensors with Ohm metter get all 0.000 with no pressure to them. I did notice the turn signal is a bit loose and slow to respond with you use it does that have anything to do with the brake lights? Also the hook up light comes on which is on the same circuit as brakes ( I believe) Brake lights are on with low air buzzer and low air light. Brake lights go off when 90 psi is reached Turn signals work Hazards work Back up light works Running lights work Are the sensors under the dash open or normally closed? Any ideas before I pay 100hr to a shop?
