When I run the diagnostic on the EATC it gives a reading I have not heard of and could not find in the forum. Every symbol on the readout lights up and stays lit. So basicaly I get the 888 with all the additional symbols for fan, defrost, etc lit up.

This started because i am currently only getting air out of the defroster, temperature control seems to be working fine, both heat and cool. I did not find a vacuum leak and was getting vacuum at the junction in the cab although I did identify a blue and yellow vac hoses that were disconnected but I could not find where to reconnect them and did not want to start dissassembling the covers until I had some more info.

Thanks for any pointers or help!

 

All 8s is a pass code for the electronic self-test.

You most likely have lost the vacuum feed to the control head.

You need to fully identify your vehicle. There are differences between years and models and we ain't psychic.

This link does not seem to work anymore. Does anyone have a copy of this?

Thanks

 

Yeah, that site went offline not long ago.

I can upload it again when I get home this weekend if no one else chimes in. On the road right now and don't have my library with me on this laptop.
