Air conditioning intermittently not blowing cold air?

Hi,

This could be a couple of things. First, I need to know if you hear the AC compressor turning on while you are getting warm air. If you do, then I suspect it is related to the blend door actuator. If the compressor doesn't turn on, it could be low on freon.

Let me know. Also, take a look through the link I attached and let me know if anything helps.

Take care,

Hi,

LOL 73 is the new 40. I have a couple of questions for you. When this happens, do you lose cold air from all vents? For example, is it lost on both the passenger's side and the driver's side? Also, I need to know if you have automatic climate control or manual. Automatic is like your AC/heat at home. You set a desired temp and the system maintains it. Manual requires you to change it as desired.

One more question. I need to know the engine size.

I'm asking so many questions because there are two blend air door actuators. If only one side is affected, one of the actuator doors may have failed or become disconnected, allowing the door to move in the right direction under heavy acceleration. It is unlikely that both failed at the same time. Note that the blend door actuator is what determines the air temperature entering the vehicle. If the A/C compressor is working properly, this would be the next thing to check.

Let me know.

Take care,

Joe

Do me a favor. Have your son confirm the belt is tight. It could be slipping and the A/C reacting when the engine revs. It's a theory.

I asked the site owner to go over our conversation. He is excellent with A/C, so I'm hoping he has some input.

Let me know.

Hi,

No problem whatsoever. Tomorrow (Friday) I have oral surgery scheduled. UGH! There is nothing I like less than the dentist. So, I have no idea if I will be able to get back with you tomorrow, but I will by Saturday for sure. If I do get back with you tomorrow, please forgive me for whatever I say. I have no idea what the anesthesia will do to me. LOL

Anyway, in addition to checking the belt, pay attention if the cooling fan under the hood turns on when you request AC. It should turn on when the AC is on to cool the condenser. Your friend should be able to hear it. See if it runs when you turn the AC on but are getting no cool air in the vehicle.

Take care and Good Luck,

Joe

Hi,

Thanks for the update. I'm glad it was a simple issue, and the problem has been resolved.

As far as the surgery, well. Let's say it didn't hurt after it was done. But today, day three since it was done, I'm ready to have my head removed next to eliminate the pain. LOL

You take good care of yourself and feel free to come back anytime. You are always welcome.

Take care,

Joe
