Got engine started. rad fan inop. put on A/c does not go on. replaced IRCM did nothing. Unplug TPS engine smooths out. still no electric to fan with of without AC on. I did see one wiring harness unconnected in the back by the firewall harness runs off the TPS wiring. I thought it might be for EGR but this vehicle does have it.. Also unplugged ECT, still no fan. Any ideas? I think if I get the fan situation straighen out, the engine would idle right.
