When you go up a hill, your car's AC vents may seem to drop off due to changes in engine load and performance. Climbing a hill requires more power from the engine, which can lead to reduced efficiency in the AC system. Additionally, the increased demand on the engine can result in less airflow from the vents. If the AC is set to a lower power setting, it may struggle to maintain the same cooling performance under these conditions.

How do you change the air conditioning vents to the correct position?
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
Why does the ac on a 1997 Chevrolet Astro quit while going up a hill?
If your problem is that the cold air stops blowing out the AC vents and transfer to the defrost or the heater vents, I have had this on my 99 Astro. There is a small vacuum line that runs from the Drive Side Valve Cover near the front across the front of the engine over the Air Conditioning components. If this line gets cracked or broken, when you are going up hill and the engine requires more vacuum for fuel there isn't enough vacuum to keep the Air blowing out the AC vents. Check the line for cracks or broken areas.
What does it mean when a refrigerant is giving off heat?
From the vents or from an AC line? If you're tracing your lines, and you feel heat coming off of the smaller lines, that's normal... refrigerants gets heated and superheated as it cycles.. the operation of AC is a series of heat exchanges.If you're getting it out of your vents, then there's a condition in your system which is preventing the AC system from providing sufficient cooling. It could be a number of reasons why, and AC diagnosis really isn't a do-it-yourself task.

How can I tell if my AC is frozen?
You can tell if your AC is frozen by checking for ice buildup on the coils or pipes, reduced airflow, warm air coming from the vents, and unusual noises. If you suspect your AC is frozen, turn it off to allow it to thaw and contact a professional for assistance.
Why is your ac blowing out of dash vents?
Your AC might be blowing out of dash vents on the windscreen as you might have turned the knob to that particular mode. It is also possible that the vent mechanism might be out of order or broken.
