Combination Switch
I need to replace a combination switch in a 97 E320.
Is this relatively easy? Any special tools required? How do I remove the cover on top of Airbag to begin with? Where are the screws for the cover? |
RE: Combination Switch
easy.
from the back of steering wheel. |
RE: Combination Switch
Sleepwalker,
There are two holes in the back of the steering wheel. I cannot see inside the holes, but It feels that I can engage a mid-size flat head screw drive. It is very tight both clockwise and counterclockwise. The tip of my screww driver was bent. I did not want to apply too much force for the fear of breaking something. What is insde the wholes and how do I get the airbag cover out? Do you have any pictures or diagrams? Thank you very much. |
RE: Combination Switch
not flathead.
it is torx. |
RE: Combination Switch
Thank you sleepwalker,
I have to go and buy the tool. Should I use alen wrench type torx or screww driver type torx. Do you happen to know what size? Thanks. |
RE: Combination Switch
torx 30 if am not mistaken.
at least 70mm long because it goes deep. too long will not give you enough space also. the L-type got more power on it. just disconnect the battery while doing it so you won't have a mercedes-benz mark logo on your forehead if ever it deployed accidentally. if need radio code, just give me your radio serial number. |
RE: Combination Switch
Thank you Sleepwalker.
Good News: I replaced the combination switch and it is working fine. Bad News: When I start the car, the SRS red warning light goes off for a fraction of a second and It comes back on and stays on. Yes I checked and rechecked that the wire plug is connected to the airbag unint. Disconnected and reconnected the battery. Now it seems that I have a bigger problem to solve. Do you have any ideas Sleepwalker? Thanks for all your help. |
RE: Combination Switch
did you mess up with that clockspring unit? check if you didn't pull it too tight while steering.
there's an open circuit. |
RE: Combination Switch
Sleepwalker,
I just bought a new clockspring and replaced the old one. The SRS warning light still comes on. Do you have any other advice? |
RE: Combination Switch
just delete the fault code.
take it to the place where they got the scanner. |
RE: Combination Switch
Thank you.
I will try that and will post the result. |
