Does anyone have a diagram of the vacuum lines for the climate control for the 190D? Mine is a 2.2L diesel, 1984, with 288k miles. Mine is leaking like a sieve and there are splices with other type vacuum hose when prior mechanics were too lazy to track the system down and replace it OEM. Now I have to spend some time under the tree replacing all the lines as a start. What's original is very brittle and needs to be replaced.
