Hummer ac problem

My ac works but the only vents that have airflow are the defrost vents. This happened after I had some leaking from the front map lights. Any advice?

Not an easy fix - sounds like either a heater/AC plenum control diaphragm started leaking, or a vacuum hose to one of them has popped off at the actuator or at the heater control, or the vacuum line developed a leak somewhere between an actuator and the heater control or the engine. You can try to pin down by checking airflow out of the defroster, ac and heater vents - if airflow is normal in each position, the problem is probably the heat/cool control actuator, the line from it to the heater control, or the heater control itself.

The airflow on heater/ac on 1999 f150 v8 switches from the front panel to the top of the dash under acceleration. What could be the problem?


Most of the time the air flow changes with a vacuum, to switch for vent to defrost to feet, it takes a vacuum to switch over, so if it does it on its on it's most likely a vacuum leak under the hood. I hope this helps.

If this happen only after you replace the battery, then you need to go look around where the battery is at, maybe a vacum line came off, vents work off of vacum.

If I am reading correctly you are hearing the vent doors moving to redirect the airflow to the vents you choose. This is normal and can be more noticeable if the blower fan is on, putting air pressure against the doors.

Heating / air conditioning control stuck to front defrost vents


There is a vacuum leak under the hood. Find the vacuum line on the passenger side where it comes through the firewall and follow it to the engine. You system needs vacuum to operate and without it the default setting is on defrost for safety reasons.

Check the vaccum line at the vacuum distribution block (to the right of the brake master cylinder). It's the smallest vacuum hose.

You have a vacuum leak. Engine vacuum is used to move the doors that control airflow for the heat and ac.
