1995 yukon breaker for pwr locks and seat

[cryptrobber]

the 30 amp breaker in slot "A" of the fuse block, controls the pwr seat , door locks and the keyless entry module.For some reason it keeps overheating and nothing works on the circuit.I bought a new breaker put it in everything worked for about 45 sec, the breaker got hot and nothing worked .I am thinking I have a short somewhere in one of the 3 items.My question is where is the keyless module located so i can unplug each item and run down the short.If anybody has any other ideas of why the breaker keeps overheating I would love to hear them, I am a little puzzled.
