95 Camaro A/C only blowing out of defrost

[dknechtlyV6]

My A/C will only blow out of the defrost vents no matter what setting it is on. I have looked for a broken vacuum line and haven't found one and I have also replaced the control switch on the panel. Is there really a hole in the vacuum line somewhere and I'm not seeing it or what? I recently rebuilt the engine in the car and still need to charge the lines, could that be part of the problem? I am having no luck any where else finding info on trying to fix the problem. PLEASE help me out.

I'm guessing it is the same (~$3.00-$3.99) part as on the 98-02.

"check valve" - "Help!" part # 47150.

This is exactly what happened to me at 132,000 miles. All you need to do is replace the little plastic valve. It is extremely easy - no dismantling the dash or any interior work is required.

Look under the hood on the pasenger side where the AC lines enter the firewall. In adition to the two big AC lines, you will see three tiny plastic lines that all come together at this little valve. The top section of my old valve had broken had broken completely off, so one of the three plastic lines was hanging down a little (not connected).

Carefully pry off the old valve from the rubber connector boots. My old valve fell apart as I took it out. There are two little L-shaped connector boots and one little straight connector boot.

You may need to carefully pry the boots off the little plastic lines in order to clean out any broken remains of the old valve. Just be careful not to kink the plastic lines as you take off the boots.

I used a needle nose pliers to pull out the remains of the old plastic valve from the little connector boots.

Lou Bachrodt (local GM dealer) wanted $10 for AC Delco part 14056648. Bennett Auto Supply charged me $5. Advance Auto Parts told me they did not carry that part. As noted above, the Delco part broke, so I bought a the Help! brand part, #47150. I've had to replace the "Help!" brand one once and am carrying around a spare in the car. The current one has lasted for several months now.

I presume there must be something else wrong that is causing these things to fail, but for $4 a pop and only a minute or two to replace, I'll keep replacing the check valve for now.

I hope this helps anyone who has this problem - it is VERY EASY to fix!
