I put Water Wetter in my car and it permitted it to run cool enough to start using the A/C. The A/C works, but takes quite a while to get the cabin cool. I haven't really used the A/C any significant amount in several years due to being worried about over-heating the engine. The questions are: where to start to get it working in good order and what steps to take, if necessary to progress. Is there a general troubleshooting guide?

Many thanks!
