A/C Not Very Cold

[thom4782]

Check the outlet temperature when it isn't cold outside. You can do this with a kitchen thermometer. Just stick the probe in a vent; set the temp to it lowest value on the center console and let the AC run for a few minutes. The outlet reading should be about 45 degrees. If it much higher, then you're probably low on refrigerant.

You can get a refill kit at any car parts shop. It's best to have a gauge so you can tell if you're high or low as you're filling the system. Over filling is bad.

See if the refill fixes your problem. If it does, then you're done. If not, take the car to an AC shop and have them look for leaks. The last think you want to do is use a stop leak product especially if the parts cheap to replace. Most stop leak products can clog up the system and lead to even bigger problems. I'd only use a stop leak product as a last resort.

If you do go down the stop leak path, look into a Red Devil product. It uses a different technology than the others.
