Re-charge battery and have it load tested. Then, using a digital multi-meter, begin tracing power and grounds from the battery through the system. Something large is likely at fault when you have a complete loss of power so it shouldn't be too hard to find. Get a chilton manual if you can to help in determining wire destinations. If you find that the battery is dead but re-chargable, after charging, check system for draw using an ammeter connected between either battery terminal and cable. Removes fuses one by one 'till you find the system that is drawing power, then check all sub systems associated with that fuse (there are some systems like your radio that always have a small draw to retain memory....ignore those)

Put ground wire back on 1995 dodge ram radio at starter?

The entire frame and chassis of the vehicle is grounded via a heavy gauge cable from the (-) post of the battery. Various jumpers are used to ensure the (-) 12 volt side of the battery is present on body panels, framework, etc. throughout the vehicle.

The *best* place to connect electrically operated devices (audio especially) in the vehicle is AT the (+) & (-) battery posts - or as CLOSE to those points as practical. Doing so, will reduce the chances of objectionable "noise" being introduced to the radio on the power leads. This is especially true when trying to connect the ground or (-) lead(s) for equipment. "Dirty" power can actually be heard through speakers as static, hiss, popping, whine, etc. The battery is the cleanest source of power in the vehicle and should be used whenever clean power is essential.

2003 Chevy Tahoe Front AC blows cold air but rear does not blow cold air

Check control switches, power and grounds, and the 'blend door' operation. If you have a 'no heat' condition throughout the vehicle you should look to make sure the heater core is not plugged, and that the thermostat is operating properly, and that the coolant/antifreeze level is within spec.

take the vehicle back to whoever serviced it, since I'm sure if its a company , they would honor any warranty, it could be something as simple as they didn't plug something sensor wise back in. If anyone else works on the vehicle after the fact , they could void any warranty, if you don't have any luck after that , we would assist you with whatever the symptoms would be
