97 dodge grand caravan 11-96 3.8L Multiple systems

Customer Question

97 dodge grand caravan 11-96 3.8L Multiple systems intermittently inoperative. Suspecting a possible bad body control module or harness problem. symptoms: infinity stereo amps cut in and out and the radio relay under dash is extremely hot. Have aftermarket radio, but it worked fine for 2 years before this problem occurred. Radio unit itself looses power intermittently as well. Instrument gauges do not work most of the time, including overhead console. Illumination of both works fine. A/C compressor cuts off intermittently while system is still warm, often at the same time the radio power is lost, but not always. Automatic locking of doors when first driving off rarely works anymore, but manual engagement via driver door switch works fine. Rear vent windows do not work at all, but front windows do. I replaced the PCM about 3 years ago for similar symptoms with the engine systems. As a former Nissan tech I know a lot of problems are repeat so if others have seen this it would save me a lot of tedious diagnostic time. Thanks.

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

From what you have described here this does sound like a fault with the body control module (BCM) itself.I have seen the BCM act up/fail before in the past causing issues like this here needing replaced.To be sure though electrical testing will need done with a multi meter.This can be a long process as I am sure you are aware.If you are taking a chance on a component and just want to replace a component I would lean towards the BCM as it can be a common failure.

Thanks Pete
