I sent all of my heater switches out to Adam to have him turn them to blue.

In the process a few of those switches have a vaccum on them and i wasnt for sure if it was safe to drive the car while those switches are out??

Thanks alot!

 

Yes, it is.

 

wtf? im confused.

what the heck are you talking about vacuum and switches?

 

the blower controls are based on vaccum operated switches. if you take the blower controls off and start the car, you will hear hissing.

 

Like I told you, if you don't like the hissing, just put a sandwich bag around the the head of the cable and secure it with a rubber band.
