I have an 03 expy with the auto climate control. The ac has been very temperamental. Sometimes it blows cold and other times it’s trying to set me on fire. I took it to the shop and they did the normal things at the time and recharged the system and checked for leaks. They didn’t solve the issue. They I took it back in for a second diagnosis and they came back to me with the sun load sensor was the issue. I had to source a used one as that part isn’t being manufactured anymore and I thought I found a working one as it fixed the auto headlight issue and initially it was blowing cold. But now it’s back to the same issue and I’m not sure where to turn or try next. If you have felt with this I would like to hear from you.
