confused on wiper door
 

Last week the wiper door quit working. Under the dash the vacuum solenoid was really hot. I replaced it. The new one still gets hot too. When I unhooked the wires the door opened and would not close, then finally it did. I have vacuum to the override but the override won't operate the door either. I hooked the two vacuum lines together and still no door operation, even with the override switch. Anyone help? Is it electrical which makes the solenoid hot? Can you not bypass that like I did ? The actuator that pushes the rod into the wiper cell pops when it has vacuum and relaxes when you shut the car off. I down load the schematics but still lost.

The wiper door on my 77 works perfect every time.

What year is your car????

You CAN by-pass the solenoid behind your tach....but by doing this...to open and close the wiper door you would ALWAYS need to use the vacuum override switch under the steering column.

With the engine running....you MUST have vacuum on the small hose that goes to your actuator relay. in order to keep the door closed.

To open the wiper door....the vacuum to the small hose is shut off and thus no vacuum goes to it and it will raises the wiper door. And this is assuming that all otehr vacuum connections/components are good.

AS for why the solenoid is heating up. .I can not say due to not having any more important information from you other than you saying it gets hot.

Thanks. Checking the relay today.
 

Yes it does but it's not as cool as my '71 wiper door and it works perfect every time too.

Mines Cooler
 

Mines cooler....literally. Mine has more airflow to A pillar cowl vents! Less restriction than the mickey mouse fancy all for nothing secret wiper door mechanism. Anyways....I am just joking around.

To the OP...

If the linkage binding during open/close?
