My eldo 97 compressor is not clicking in (no relay sound when turn AC on or off). I thought that it may be low refrigent so checked lowside Freon pressure (with compressor off, it is 100 PSI). I removed low pressure switch connector, short it but there is clicking sound of [COLOR=blue! important][COLOR=blue! important]relay[/COLOR][/COLOR], so compressor does not come on. The low side prresure without compressor remains 100PSI. I checke codes and cleared all the codes. There is only one unrelated code PZM2473 current.

Any suggestion please what to do. Will removing a battery terminal and reconnecting my reset and let the compressor on? Could it be the compressor relay itself. How to check the relay?

Thanks
John

You should be able to jump the relay terminals in the fuse box (or wherever the relay lives) to see if that kicks it on.
