Hi all,
I am still new on this site as I have recently purchased my 95 S420. I am still finding out about all of car's functions and at the same time also finding out what function works and what doesn't. I have done a lot of research on different areas of problems and found out that most of them are all common in these cars. Some of them I have already found answers to and others I have not yet. So I have a few general questions and will appreciate if I could get some answers to those and some corrections to some of my own conclusions.
1: all the power windows work fine but only through the switches in the front. Both window switches on the back doors dont work. I assume its just the switches that need replacement? Is it just the top switch part that normally goes bad or the whole unit including the wires need replacement?
2: Power lock system doesn't work. Light flashes on both doors but do nothing. The manual key insert only works on the passenger door. Locks can be pushed down or pulled up by hand. But during all of this, no sound from the PSE pump at all. On pressing the central locking switch, a noise can be heard from inside the dash on the passenger side. Not sure what that is. But nothing happens.
Have read a lot postings on this topic and my conclusion is the PSE pump motor or the entire pump needs replacement. Please correct if I am wrong.
3: Door soft close only works for both the rear doors. I assume its the vacume motor or assembly inside the front doors is bad.
4: I have a rough idle and hesitation when taking off from a stand still. Once it starts to move than the car all of a sudden gains normal power and hesitation goes away.
My research tells me that I have a bad MAF. Today I disconnected the wire and the idle became normal. I am getting the codes for MAF. The accelerator pedal starts working after being pushed almost half way down. Up till that point it seems as if the pedal is loose or there is a play in it. I thought it was related to the rough idle and the hesitation but I just want to know if this is normal for these cars or no.
Any help is appreciated. Thanks in advance.
