I have a 1995 Mustang with a 3.8L V6. It currently has 157,800 miles on it and is in great condition other than the few problems that I have at the moment. Up until now, I really haven’t had any problems worth mentioning. I’m going to do my best to explain everything as clearly as possible.

Here’s my first issue. If I start my car with the air conditioning turned off, the air works fine. If I start my car with the air turned on, it comes out of the defrost vents on the dash. If I turn my air off while I am driving and then try to turn it back on before I turn my car off, it comes out of the defrost vents again. Sometimes it will be working fine and start to come out of the defrost vents while I’m driving but after about 30 minutes, it will start working properly. I don’t know what could be causing this but it is occurring more and more frequently and it’s essential that I have air conditioning due to the fact that I live in Florida.

Now for the other issue. I’m having acceleration problems as well. Yeah, yeah, I understand that I have a 3.8L so I know it’s not going to get up and go like a GT would. I’ve just been noticing that it has been less responsive than it used to be. I don’t know if that could be due to the fact that it has 157,000 miles on it or if after so many miles it just gets slower. It just doesn’t feel like it has power anymore. From a stoplight, it accelerates very slowly. It used to be slow to come out of first gear since I got it but it would quickly go through the other gears and I would be going 60mph before I knew it. But lately it is slow through all the gears. It takes about 12 seconds for me to get up to speed. Also, if I need to pass someone, it takes about 6 seconds after I push the gas pedal to respond and go into passing gear. I just remember it being more responsive than that. It’s getting to the point where I no longer feel as confident driving on a highway due to my car’s poor acceleration.

I hope I explained all of that clearly. Any help would be greatly appreciated.

Thank you.

1st issue is usually a vac leak. The HVAC defaults to floor/defrost with no vacuum. In order to go to the panel vents, vac needs to be applied. There is a line in the center of the dash which draws the flapper to change it. You'll need to poke around and search for it.

2nd issue. When was the last time you did a tune up? New plugs wires. cap rotor, fuel filter, air filter, etc?? Is the check engine light on?

Had the same problem with my son Mustang, There is a small vacuum line the runs from a tee on the driver side fender and across firewall, there was a break where it went to a joint, fixed it and works fine.
