Hi, hope you're all staying warm. My '90,a/t,all stock has 2 problems. I don't know if they're separate or possibly related. The 1st is the clicking sound(like a relay)from under the pass. side dash. The interior lights won't come on until the clicking stops. Pressing the brake or opening the hatch usually stops it. The 2nd is the service ABS light coming on. The vehicle rolls the required distance but the hydraulic assist does not kick in. The ABS light comes on, the dash lights will flicker continuously and the engine runs rough. Turning the key to 'run' position for a few seconds before starting sometimes helps. This problem happens most of the time but not all. Any suggestions would be greatly appreciated, TIA, Bob.
