Please Still Have Terrible Tweet Sound
 

Please if anyone can hlp me? I might have posted n the wrong place the first time, so I will try posting again. Forgive me if I am doing this wrong.

I changed all my fuses in the fuse box I can reach. I got new breaks and pads
and I still have a tweeting noise. If I stop my car an it cools down the tweeting and it goes away so the mechanic's can never hear it since I have to turn my car off or let it run and put it in park to go and get them and then of course it goes away since the parking break has been on for a while???
I am going crazy, since I cannot afford a new car now and I have to go for medical treatments that are not that close to home with my car tweeting louder and louder all the way!!!
Please can someone tell me when to look for other fuses aside from the box
I can reach under the hood and in the trunk of and 1992 500SL.
I will be most greatful:(

P.S I read on another board to pump the breaks hard 30 times but that only helped for a short or have the mechanic bleed the breaks and reset the computer. I asked the mechanic if he did that they don't bleed breaks but they did lt the air out??? I have to believe him since I wasn't there....


Only car 1992 500SL
