Howdy. I changed employers, and as a result, changed driving patterns.

I recently became painfully aware that my AC does not cool my car unless I am flying down the highway. OK. that's an exaggeration. But it definitely does not cool when I drive a mile to pick up my daughter, and wait in line at the school.

I got out and checked the ACC fans on the front of the radiator. No movement. Outside temp was close to 90* F, dash fan was blowing strong. If my drive takes me to the highway, or at least on a road where I can go 35-40ish, then I don't really notice an AC issue.

I have been searching for threads related to this. My electrical skills are not good. I am not clear on instructions like " jump the wires connected to the pressure switch with pigtails on the AC drier". Does this mean bypass the switch by connecting the two wires directly? Same question for "jump the wires in the 2-pin connector". Also, where do I find the pressure switch? Or the AC drier?

Thanks!
Tom Lynch
