This question has probably been answered. I've done my search but couldn't exactly find a specific answer that I'm comfortable with. I have a 1987 190e 2.6. It seems that my A/C works only when the weather temperature is cooler, like in the evening or early morning. It seems that when the car or weather is hot the A/C compressor doesn't come on and all I get is outside air. I know there are various sensors that this could be. Just wanted to limit to at least 2 before I start purchasing and replacing sensors. Hope someone can help!
