My air conditioner had blown not-so-cold air for the last year or so. Occasionally, it would blow warm for short periods of time.

I started having a slow crank so I checked the batteries, and one of them was bad. Probably had been bad for a while. I replaced both batteries and now WOW- ice cold A/C!!! The A/C had not been getting enough voltage.

I am also getting the starter rebuilt since the bad battery and parasitic battery drain has weakened the starter.

I made this post in hopes that someone who searches these topics, like I did, will find this solution.
