The gauges are all plugged into a cluster, this cluster gets power and ground, it's connectors may be slightly corroded or the circuit board may be shot. Try unplugging and plugging it back on. The weak point of the air bag is it's connector, take off the 4 10 mm nuts, unplug it and plug it back in. Make sure that the mounts are properly grounded. Did someone leave a ground strap off? Check them, the engine must be attached to the body and frame, while at the same time insulated with rubber, that is why these straps with clips on them are used. They get thrown away, I know, I have a few in my box. A ground fault can screw everything up. Also, after all this, make sure this battery ground is good and that it is not hooked up when you do any work at all, especially on the air bag. Leave it disconnected over night. The belt may have a bad compressor clutch it is trying to drive, the cars are set up to give you heat, but with no moisture in it, so it may be coming on. Change the self adjuster mechanism if it hasn't already been done and be sure the pulleys are checked and the alignment also. Hope I helped you somehow. Is there a splash shield left off from the trans job? It could allow moisture to get into the front pulley drive system. Good luck and thank 2carpros and all the techs. And employees, ok?
