I downloaded the manual and have searched the forums. I am still confused?

Any tips?

when I bought the car, they told me to pop the hood and remove the relay to turn the fan off and on? I messed with swapping some relays and thought I fixed it, but found my battery drained and a very hot relay? WTF? something grounding out?

also need some advice on how to get the vents working again, seems to be no vacuum?

Your wisdom and experience is requested and appreciated.

The XT6 vents are all electric, no vacuum.

 

I will look at the diagrams and see if I can help you figure out the issue.

 

Which relay was getting hot?

Blower fan or Radiator fan?

 

Radiator fan should be direct power from fuse and ground through temp switch.

the relays under the hood by the air filter.

I've identified the AC relay, and the rad fan relay, there is a fuse block and one other relay I cant identify? can"t remember which one got hot, but when I got the car one was melted

 

and the vents are stuck on defrost,

Are you talking about the blower for the A/C or for the Radiator fan?

 

A/C uses a relay to turn on the fan (provides ground for fan not +) .....but the main power for the fan comes straight from a fuse and then the Thermoswitch should ground it when hot.

 

Vents stuck is also an electrical issue..not Vacuum.......Does the switch pod for the vents seem intact?  or are the buttons funky?

been messing with the relays this morning, i think it's sorted out.

I printed out the wire diagram and matched the wire colors.

The switch pod seems fine, buttons OK. if it's electrical could it be the motor?

Thanks, 

the relays I had around were from a Legacy, I had to swap the pinout on the connectors to work, or did the last guy swap it wrong?

I followed everything according to the wiring diagram, and I think the rad fan relay is ok now but the ac is all busted anyway so I'm not worried about that.

I will be wiring a manual control switch for the AC sub fan, for extra cooling.

actuator for the vents still not responding.

what is the other fuse for next to the inline AC fuse?

where is the sub fan diode located?

As far as I know the square Legacy relays are the same pinout as the old round EA ones.......although the Fan and A/C relays in an xt6 may not be the same so iDK.......Not much experience with the 6Cyl XTs.

 

For the vent door....I would suggest checking for power on the R/Y wire from fuse 12 to the mode door motor, and the switch itsself.

 

also Verify the Black wire has ground.

Too bad......There were no XTs there.

 

You'd have won first place!

 

Keep working on it.

Still working on it, and still finding and breaking more, 

relays are still bad, have to check temp sensor, but will probably just end up by-passing it all, so I can have manual dual fan control.

alternator near dead, I have another but don't know the state of it.

where can i get a new belt tensioner, this one is all messed up.
