With the harness connector (to the relay) disconnected, I see no voltage on any of the 4 harness wires feeding the relay (I assume that 2 should be 'hot' with the a/c switched on). With the relay connected, there is no voltage going to either the fan or the compressor (expected). The fan works when jumped directly from the battery. This all seems to indicate (to me, at least) that the realy may be ok and that something further upstream is the problem.
Again, I have already (again) checked all fuses, replaced (apparently unecessarily) the a/c switch, verified the function of the fan and compressor, as well as the system charge.
Is there a temp sensor, or some other control in this loop that I still haven't checked? And if so, where is it located? Thanks again for your help so far.
have the same problem?
