No air from dash vents FIX Grand Marquis Crown Victoria

Car had no ac from the dash vents. I couldn’t find a leak and when I checked the vacuum supply inside the car there was very little. Not enough to move the actuators. I traced the issue back to the check valve and replaced it. Works fine not.

Thank you! I have the exact issue with my 2011 Crown Vic

Glad it helped

[@kwick818]

mine is stuck blowing through the main vents. I think it may be ice build up though, so ima hit it with a heat gun. Thanks for the vid, first one ive seen that gives me something other than "dont set you knobs to off"

Do you know where the INTAKE AIR TEMPERATURE SENSOR is located on a 09 Grand Marquis?

[@donovanmcbride4315]

Should be part of the MAF (Mass Air Flow) Sensor located near the air filter

Where would one find this part

[@EnzoGFXDesign]

Rockauto probably has it

[@donovanmcbride4315]

I’ve always gotten them from the dealer. It’s pretty cheap. Like $10-12 where I live. Maybe google the part number and find one online.
