The unit wont power up it is stopped at the first power relay. iT SEEMS THE POWER RELAY IS BAD. cAN IT BE FIXED

The relay is used to take the start capacitor and start winding out of the circuit once the compressor has come up to speed. Using an ohm meter, no power to the unit, and relay disconnected, you can determine if the relay contacts are open or closed. With no power to the unit, the contacts should be closed. If they are open, the relay is bad. However, the start capacitor could be the problem.

check the relay and see have you got power the relay might be bad and could be stopping the power going to the 30am fuse

Sounds like your power transformer is bad. You might also check the power board for cracks. This model had a history of that.

Relay in controller stuck closed. new controller required - may be a pcb type that can be fixed with a new relay

Have your main power relay replaced as your problem is the typical symptom of a bad main relay, when it gets hot after driving and trying to restart. The running rough problem might be your center engine mount. Have it checked to see if it's bad.

The power for the fan comes from 2 relays in the
junction block on the left fender. One is a high fan relay 40amp the other is the low fan relay 20amp.
If either one is stuck, it will power the fan. Also if the
engine coolant temp(ect)sensor is bad, it can send a
false signal to the engine control module(ecm) and powering the fan. With the engine cool, if the fans still
running. Unplug the ect sensor(on thermo. housing)
if the fan stops replace the sensor. If not pull the relays one at a time. And see which one stops the fan. If none of this works it may be an ecm problem.
Hope this helps.

Most vehicles have relays to run different things and in most cases the relay gets power before the fuse so if you pulled the fuse the relay is more than likely still getting power. It may be that you just have a bad relay. You can also find the horn itself and simply un plug the power supply wire going to it.

Then you are possibly have a bad relay or a bad switch. Check the relay under the hood and make sure it is good. If the relay seems to be good replace the switch on the dash.

Turn off the power to the air handler(indoor unit). Remove the access panel. From the motor,trace the wires back to the fan relay. One wire will probably trace back to the incoming power terminal. The other is the fan relay. It could be intermittent thermostat signal to the relay or a bad relay.
To verify if the fan motor is good,you can remove the one wire from the relay and re-attach it to the other side of the incoming power terminal. If it runs OK there,replace the relay. If it does not run,replace the blower motor.

no ac power you are hearing a 12 volt relay tellling it to come on but there is either no ac power or control ac relay is bad and you will have to replace control unit to ac useually arond 150 depening on unit
