    My W203 C320 2002 is having problems with the parking sensor (both rear and front), key lock and the electric passenger seat.

    My mechanic believes that the cause is the rear SAM Module, is that correct?

There must be somekind of amp draw or else you shouldnt be having any problems,this may sound wierd,and also may be a bit of work,try disconnecting the alternator for a night and see if your problem goes away,ive run across this a couple of times,also,seat control modules are known to cause draw problems in c and clk classes

My tale lights our out and windows will not go down is it a fuse and what fuse do i need to change


all windows dead? not just drivers? (not stated)
all park lamps dead, all 9 outside lamps dead??????? 3 rear
2 front and sides.? dead, with HL switch to park position?

correct step 1 are fuses
step 2 scan it, the BCM will tell you why it can do its job.
it will.. in most cases.

there are 2 ways (and more) to check fuses.
1: test them all, works every time and takes no knowledge of system complexity. (using ohm meter or voltmeter)
2: read he operator guide and read fuse page. its there. lost that.?
3: read the FSM book or at alldata.com and it there. for sure.

can i assume all else works?, and drive car at night)???????
03 WJ jeep, it is , I have WK 10

so windows can go down so cant test up. on all doors.
Tail lamps. 03.
so front parking lamp work but not rear tail nor rear license plate lamps? that it? the parking lamps is the better name
other wise the front tail lamps out sounds funny.
JB box Fuse 6 runs all park lamps front rear sides and license
so did you miss those lamps?
the relay that runs the run all lamps. all park lamps. lots.
the BCM controls (computer body) controls that relay.
so if main battery is weak the BCM will go nuts. does car drive ok at night
headlights bright?
there is no common demoninator for park and windows.
besides the BCM. it controls 31 major things in the body.
ill check that next. but not windows.
window motors
fuse 12 runs this. PDC fuse box under hood. 50 amps (huge)

ok there is a link from dead parks to windows
that is because the BCM sees you operate the switches
then sends serial commands on the CAN/PCI buss to the door window controllers.
so if you had scanned the pcm , and say gross can buss errors.
then bingo
why not get the car scanned first and show DTC error you have
I'll BET LOTS>!

do the 31 other things work like wipers.
door locks dead.


drive to any shop and say scan my car and get all DTC errors , not just 1 of many.

Location transmission control module


You need it in a shop to find out why
The new battery won't last long like that
The car has to be checked for parasitic
current drains
Most likely some module is not going to sleep when
you get out & close the doors

2004 mercedes clk reads coolant visit workshop. The coolant level is ok, but the radiator fan keeps runs on high as long as the car is running. I replaced the coolant level sensor which did not solve...


It could be either the left front fuse and relay box,left front sam or the engine control module. Basically it's in a safety mode right now because the engine control module is not getting the coolant temp. The early clk's had this problem when they came out with the new body style. Was a common problem for awhile.

My battery keeps draining down at night it's a 99 dodge durango


you have something draining the battery,check for any lights that might be staying on,interior light,stop light under the hood light(if any),glove box light trunk light, if you have a multimeter with amp testing capability or an amp meter you can check where the drain is by removing each fuse & put the probes on each side the terminals until you find a drainage,that way you might be able to find out what is draining the power & rectify it......hope this helps......cheers

It wont start and the battery is fully charged.


a meter hooked to the battery or the meater in the dash board??? if it reads 8-10 when trying to start, either the battery is weak or the starter is drawing too many amps. Who tested the battery/ starter and where. it should be tested in the truck, not taken off to some parts store. have you verified good ground?

2003 VW Beetle battery drain


I think I remember running into this once before and found a factory rear speaker amplifier in trunk that stayed powered on then we replaced the amp and the new one did the same thing . then checked radio coding and it wasn't set to proper code so it didn't know to turn off the amp. changed the coding to correct setting and bingo problem solved. hope that might help but coding can only be done by dealership.
