It started with my gauges bouncing all over going on and off , then it felt like the brakes were on and I had to give it alot of gas to get going.now the dash will work when I turn the key on but as soon as it starts it goes out with the exception of the oil pressure and the charging gauge. The transmission isnt working right at all and I dont dare drive it anywhere. The fuse box under the hood does not test right, only about half of it has power and I am at a loss there! There has been electrical probnlems with it ever since I bought it.

My customer complained of a transmission failure involving, but not limited to a DTC p0785. I asked my customer if the involved vehicle (2000 Chevrolet Blazer) had any dealer or after market accessories installed, customer adamantly replied: no, "bone stock GM." my customer was not aware that the involved vehicle had a theft deterrent system, manufactured by "karr" and distributed by audiovox with installers nationwide. I have been actively involved with GM dealerships for over forty years and possess a wealth of experience in parts and service experience. I removed the suspect security system and repaired the damaged wiring which resulted in the improper installation. In the past week I have been confronted with four customer complaints which resulted from security systems, aftermarket radios and including aftermarket headlamps. …

Upon approaching the driveway vehicle suddenly made a noise. Steering wheel felt funny. Also, front left tire turned in the opposite direction that vehicle was going. When this occurred vehicle skidded. Consumer depressed the brake pedal to stop. This occurred because the left front lower ball joint came apart, and the front right ball joints were starting to show signs of the same failure. The entire front suspension assembly needed to be replaced. Also, automatic transmission slipped when shifting from first to second gear. Meanwhile, while driving in over drive mode, the over drive disengaged and vehicle speed was reduced from a rapid pace to a very low speed. This failure almost resulted in an accident. Dealership determined this was caused by a failure in the torque converter solenoid.
