I have an issue with my 85 wagon. My wiper delay time is about 1 second, which might as well just be on the low setting. My 2 1980 240's have about a 4-5 second delay, which is almost perfect.
In searching, it appears there may me a wiper relay that controls delay. Here is where I got that info:

W126 Wiper delay funtion fixed!!

Where is this wiper relay, if in fact that is what controls it, and can it be swapped out with an earlier year that might have a longer delay?
Thanks all.......
