I have a major problem and am just lost on where to go with it. I installed a new radiator and fan. I hung the fusebox to my hood to make more room. I also had to move the airbox surround to get the radiator out. Never disconnected either. It now is throwing a tcm code and several heater codes. The security system is disabled. It has to be on a charger to keep the battery charged. Alternator and battery are fairly new. Something is killing the charge. Every light known to man is on. It was running but very sluggish. The speedometer would jump when hitting any kind of bump. The last time it moved had to be driven like your great grandpa was driving it. Transmission has been slipping for quite a while but nothing like what it is doing now. Any kind of help would be greatly appreciated. I love my car and hate that I can't drive it. Thanks a lot.
