Icon4 Vacuum Leak Help!

Alright I have searched and searched without finding any specific answers.

Whenever I accelerate, either from a stop or already moving my vents go from panel to defrost. I have checked the vacuum ball by the intake and it doesn’t seem to have any cracks or damage. I have looked behind my glove box and behind the hvac controls and all the plugs are connected and I have looked everywhere I can figure is vacuum related in the engine and made sure the plugs are tight.

Where can I look from here?? I'm sure it is a vacuum leak but I have no idea what to look for now nor how to fix it.... not constantly having vents nor ac sucks with this heat =(

Chances are good that it is simply the checkvalve on the vaccuum ball.

It is the rubber fitting where the engine vaccuum line attaches to the ball. You can usually get them at the auto parts store in the HELP section. You can add an external checkvalve and leave the bad one in place, if necessary.

It is common for that particular vaccuum line to get rubbed through or cracked. Same goes for the heater control valve line. If you have a heater control valve, it will be located on the heater hose near the firewall. Your leak could be there too.

One method of checking for an engine vacuum leak is to use starter fluid and spray it in the area's that you suspect there may be a leak. If there is a leak the engine will suck the starter fluid in and you will hear the engine rev up momentarily due to the starter fluid. This method can atleast help you find the area of the leak.
