AC stay on
MY Son has a1995 ram 1500 with 318! Flushing radiator this morning I noticed heat wasn't getting hot and ac compressor was running? I had heat on in truck and running wide open ,it wasn't cold air but not hot either? I pulled relay on compressor and then heat was working correctly? When I put relay back on compressor comes on even though I have heat on climate control? I tried changing relay but same result? Any advice is welcome! Thanks

Yup. It is only which vents are selected. Any setting that includes defrost, will have the compressor running. I think any setting that includes the dash vents will also have the compressor running...... On the 97 and older trucks, it also depends on which way you turn the fan speed control ****. To the left will allow the compressor, to the right will only allow it in defrost/dash vent modes. (or something close to that.)
