Can anyone tell me the location of it? The A/C hasn't worked in years and I am going to trouble shoot the problem this weekend. doing research, I've read about the relay but can't seem to find it.

Any tips on trouble shooting will help too. When I turn on the AC, it blows but doesn't cool. the clutch on the front of the compressor doesn't engage.

 

Lookup Cruiser54, Renix is strong with this one...here is a diagram and I think it applies to the Renix 4.0 as well but will defer to the many other Renix experts for any other data...

 

This here is in my sig, along with a link to Cruisers tips and some other misc.
