Are you talking about the air speed or temp

twittyaustin

the air speed. i cant get it to even cut on at idle it only it blows but the tinyest bit when driving

OK don't add anymore freon. I would start at the fuse, then the blower motor resistor then the blower motor itself.

okay i was just told it needed some to even cut on the compressor

twittyaustin

anyone?

Air flow and ac charge circuits are two totally different things. Sounds like you have a blower motor not coming on. Check fuses first

Your a/c has nothing to do with your problem. Its all about airspeed which comes from your blower motor. You will blow your compressor up if you add anymore freon.

yup it was just the bower motor fuse thanks

Now you need to go to a good shop that works on air conditioners and get the system back to the proper level. You can do a lot of damage by adding that can of refrigerant. I assume you just added it and didn't put the proper gauges on both sides of the system.
