We have a crew cap, short bed, Z71. When traveling and in traffic, we will push the air re-circulation button to keep out the exhaust from other vehicles. However, we have noticed that pushing the air re-circulation button does not stop the fumes from coming into the cabin (e.G. We can smell the diesel exhaust from the truck ahead).
Looking around on the internet it seems that since 2014 GM has limited the air inlet vent to 90% closed even when the air re-circulation button is pushed. Is this true?
Is there anything I can do to change this? I am not sure where the air inlet vent (and actuator are on this truck).
Thanks in advance,
have the same problem?
