A/C codes on low 35K mileage '02 e320 W210
No A/C won't take R134, have two codes that are not coming up in any search:
B112D, A/C interface the reception line has short circuit to ground
B112E A/C interface the reception line has short circuit to battery voltage
Can anyone help with these codes please??
possibly related is the climate control light bulb is out, changed bulb, still out...
I have done the A/C diagnostics and understand the other codes as follows:
B1231 so I changed the ECT sensor, that did nothing
B1232 refrig Pressure Sensor, have a new one have not replaced since I will almost certainly need a evac and recharge and don't want to loose compressor oil un necessarily
B1233 refrig Temp sensor, have one will change when evac an recharge
I have run the on board diagnostics and checked sensor readings
#5 ETC sensor reads E
No good indies in Maui Hawaii... Please help
