Hello all. I have a 1997 Sunfire SE 2.4 with the 4-speed automatic. Recently, shortly after having my a/c recharged, my Check Engine, ABS, and Brake lights lit up in the dash. They come on every time I start the car. I now have a firm brake pedal, and my a/c clutch will not engage. Sometimes, under the hood near the ABS module, I will hear a sound that sounds sort of like the old dot matrix printers. The a/c system was properly filled at the shop. The compressor is good. All fuses have been checked and are good, and I cleaned the electrical contacts and grounds. The shop told me it must be a bad ecm or a short somewhere in the wiring. So, I replaced the ecm with another used one, and still have the same problem. All wheel speed sensors are connected. I also left the battery disconnected overnight, and that didn't help. When I pulled the codes for the Check Engine light, I only got Shift Solenoid A and Shift Solenoid B pending codes. Has anyone experienced a problem like this? I will try anything before taking it back in for diagnosis.
