i have a problem with cabin electric. i will try to describe.
often the front windows and mirrors dont work, then sometimes its the same with back doors, cabin light, trunkopener (mostly from outside) at the same time the whole central locking system dont work, and when it is badest the wiper, horn and blinkers do not work(hazard still work).
i have tried the mecanic, the first time they said low power on battery, ist fixed. That is not true, it always starts even in the cold conditions where i live.
two days later driving in the rain suddently the wiper began to run wery slow, and after that nothing worked. then i measured battery and it was fine, i checked all batt connections, disconnected the batt for the night, but that didnt help.
then i tried the mecanic again, he said that the pump under seat had run warm and print/component was no good, he also said that the car was working and that i could try to drive it for some time, but that i had to have a new pump. He tested generator batt etc. and found everything ok. i think that it was my luck he didnt have a new pump(1000$).
got home, drove for 5 or 6 days, then it was the same again.
then i took the pump out to see if that would clear the problem, but it didnt,( there is no moisture or oxidation near the pump) i took it apart to to see if it had any sign of being warm, it didnt.
i have checked all + and - wires for oxidation.
then i tried the mecanic again. this time he said that it was the roof unit that was short to ground in can system, he changed it with a used one and was happy to have found the problem.
after 4 days it was the same again, and after having used 1800$
and the car isent fixed at all i dont know what to do.
i have asked the mecanic how he determined which unit was bad, and he said that he pulled out the units one by one until the rest would work.
i am going to try the same, but can anyone help with info on where the units are placed and what they do, or help with any surgestions on what to do.
maybe i can get a carsoft/interface for the kodes.
