I was checking for a vacuum leak because of what I read for wild vents and found a broken vac line. It goes from a T on the right side of the motor through the fire wall with the A/C lines.

Any idea what its for and will it hurt anything running it the way it is for a few weeks. I will be replacing the dash, heater core and a/c evaporator at that time.

 

If your vents still sorta work, that line probably goes to the vacuum reservoir under the plastic cowl piece at the back of the engine compartment. Just use a piece of rubber vacuum line to splice it back together.

 

I tried the vents and that is what the line is for. Now I only have defrost so I will be fixing that problem in a few weeks.

Thanks
