For quite a while now wierd things have been happening. Start car and gauges are dead after 30 seconds or so gauges "come alive" again and are fine.Have ignored problem and then when you start turn on air everything is dead. Drive 4 or 5 blocks and it comes on fine also same problem with all power windows. Service engine light on the right cluster comes on , but when I put on my scanner to read the code there is none. Finally a severe problem has occured with the turnsignals-highway flashers-blinking very very fast. I was told it's a BODY CONTROL MODULE. Does this sound correct? Where is it located and how much do they gennerally cost? Any input would be appreciated. Thanks

You have a dead battery an you have to charge it a lot ?What year make an model vehicle . If the doors are locking an unlocking all the time ,it's draining your battery . Depending on what controls the locking system ,relays or a control module that could be the problem . Most all vehicles have a BCM - body control module . Some auto makes just call then by different names ! GM calls it a BCM , Ford has called them GEM - generic electronic module or SJB - smart junction box . No matter what they call it , it has logic programmed into it an it controls relays to turn thing's on an off . You should take it to a ASE certified repair shop where they have diagnostic tools to find out what is wrong !
It may seem like the problems are related, but they most likely are not at all, unless it's an actual battery power issue. Your fuel gauge consists of 2 parts and wires to connect them, the sending unit, which is in the gas tank connected to your fuel pump on your truck I believe, and the gauge itself inside your dash. It is most likely your sending unit/fuel pump which sucks cause that's like $350, altho easy enough to replace yourself with very little gas in the tank. As for the radio check fuses, and AC I have no idea...
Sounds like the body control module(BCM) has died. Do a relearn. Turn the ignition on (don't try to start) for ten minutes, turn it off for 30 seconds. Do this three times( have a battery charger on it). After the third time, try to start. If it does start, then have the codes read. It could be wiring, bad communication from computers. ( a U code) Or the BCM is dead..
I'd have fuel pressure tested. I had a 95' did same thing. Cold winter day, worked fine, as soon as it got warmer, or hot out, it would quit, and re-start 20 minutes later and go for a distance then die again. If I parked in the shade on a hot day, I'd get further before it quit for the first time. I started carrying a fuel pressure gauge with me. Cool in the morning my fuel pressure was up to spec @ 49-50psi. Once it got warm/hot out and it died, Hooked up gauge and it was at 2-5psi. Let it sit and cool off 20-30 minutes, pressure would jump back up and run good until fuel pump got hot again and then pressure dropped off and car quit. It sure sounds like the fuel pump, but the hard part will be getting the car to the shop at the right time, or they will need to let it run on the lot until it quits to confirm the pressure drop. One thing you can try is when car quits, have a can of WD-40 or quick start with you and a screwdriver. Loosen the clamp on the air intake hose where it connects to the front of the throttle body and pull it off. With vehicle off, turn throttle linkage so the plate opens up enough to spray WD-40 a second or 2 in the throttle body. Then try to start it. If it starts and runs momentarily, then you can be pretty sure it's fuel related and my guess is the pump needs replacement.
good that can be replaced and the cost varies from one state to another if you succeed in disarming a car you can go look for the less code that has the BCM and get an equal or the same because the final numbers would not you work
The body control module on this vehicle controls the gauges, radio,
door locks, windows and wipers.... (More) The body control module on
this vehicle controls the gauges, radio, door locks, windows and
wipers. When this module goes out all sorts of crazy things happen to
the car. The module is located inside the car behind the fuse panel. I
have had this module go out on three caravans and it is very expensive
to replace. Chrysler is aware of this problem. A mechanic told me that
they were going to issue a recall but it did not impose a serious
enough safety threat.
The fuel filter is on top of the fuel tank is visible and brings with her 3 hose couplings
