Ok. After wedging myself upside down under the dash I was able to see the hose fitting. I replaced the vacuum hose with new stock and hooked it up. No joy! I think the switch is sticking/messed up.

I did buy an electric motor replacement from Classic Chevy Parts a few days ago. I was actually hoping that the wipers might be some low hanging fruit on my gig list. Thought getting and hooking up some new hose would solve my problem. I was going to save the electric wipers until I rewire the entire truck.

I am having significant issues with the signal/brake lights at the moment. The problem is currently too hard to describe. I'll get back to that in a different post. That is why I'm reluctant to attempt an electric wiper install. I might just be adding to my problems.

Back on subject: I did manage to get a little movement out of the wipers after messing with the knob for a while. The only way I could get the wipers to move a little was to stomp on the gas. While the engine was hesitating/sputtering (did I mention that it doesn't accelerate very well) the wipers would move. Once the engine settled at the new RPM that would stop. That is actually the opposite of what they used to do when they were working. Before they would work fine at idle/constant speed but would bog down under acceleration. Does this sound familiar to anyone.

Needless to say, this is getting very frustrating. All of my repairs seem to fail.

As a refresher I am running a later model (63-69 I think) 250 in my 58 Burb. With the engine swap, its hard to tell what is original under the hood and what was swapped out.


Thanks
