Hi Forum,
I had a new hood and hinges put on my ’91 350SDL and when I got it back from the body shop, I noticed it shifted hard. Thanks to the forum here, I was able to determine it was a vacuum problem and not an expensive transmission problem! I traced the leak to this spot and I tapped up the hose here on the left to stop the air leak from the hose on the right that I am holding, to make the tranny shift smoothly again for the short term fix, but want to get it right.
I seem to have found the culprit, a vacuum hose to nowhere, right around where they were working to install the new hood hinges - said they had to remove the fron left fender to do it.
I have no decent reference material to see where it should go. I have included a picture of it in case someone knows off hand where I should start digging.
Since my climate controls don’t switch from defrost, I am looking at this as the likely connection, but where should this hose enter the car? Where should I open up the car and where should I connect this tube? What will I have to remove? Argh!!!
It is black with a white pin stripe.
See picture
Thanks all!
