I have a quick question. There seems to be a wire coming out of our battery's positive connection cable. We never noticed it before. Can anyone tell me what it is? I'm guessing for quicker and more accessible testing? Thanks

Probably a battery tender. Where does it lead to? Is there a connector at the end? A lot of battery tenders/trickle chargers have cables that are installed to the battery terminals and then you plug the cables of the charger into them.

A picture would really help.

Yes, I want to get a picture but I'm not home now, but I'll get one up in a few hours. I looked at this diagram and see a section coming off the positive cable, so it looks normal. http://cdn3.volusion.com/ekutc.vrlsy...jpg?1347959337

The C5 OEM Positive battery cable splits into two wires. One wire goes directly to the starter solenoid and the other goes to the engine fuse box B+ terminal

The Negative battery cable also has two wires. One goes to the engine block and the other goes to the frame Chassis Ground G-104/108

shaob

let me try a picture now


yes, you're right, it's connected to the fuse box, but loosely. What are the second wires for? Thanks a lot! just hoping it was normal and not some add on. Are having problems with our AC and have been looking at other threads on that.

shaob

thanks, yes that is what it is I'm guessing. Was just hoping it wasn't some mod we didn't know about.

shaob

now just need to fix the AC problem. Tried the fuse 27 fix and adding 134 EZ chill refrigerant, and unplugging the battery, but passenger side still blows hot!!!

I have NO idea what that wire is but it isnt stock. The terminal on the fuse box (in that picture) has all the correct connections.

Find out if that wire is powered. If it is, I strongly recommend covering it in electrical tape or removing it.

Use the DIC and read and post the DTCs

Looks like the wire has an eyelet connector, it's tough to make out in the picture. That connector was once attached to the 12v stud at the end of the fuse box, so it's a power wire to something (?). If I had to guess it looks like it could be a power wire to a stereo amplifier considering it's loomed with the power wires that feeds into the passenger compartment.

That would be my guess as well, but it should be fused somewhere before the firewall.

I installed my battery tender cables to the ground and the B+ terminal on the fuse box. It is a clean, safe installation. That is not good.

shaob

it does have a Pioneer Sirius radio installed

these are what came up now

Neither of your temp door actuators are functioning Either there dead, broken gear of not being powered

Can you hear them cycle when you pull and reinsert the fuse??

shaob

great! I'll try and test later for sure. Have an appointment at the dealer tomorrow too. If the actuators don't work, do you think they're the ones under the dash near the radio? or are they located some place else? I'm looking at another post you helped someone out with the same issue now. Great pictures.

shaob

never mind that last question. I see both are behind the dash then now. interesting. those control the heat and air temperature of the air conditioner then? Do you think it could also be the ambient air flow sensor? Or that wouldn't be part of the problem

Bill Curlee

OH BROTHER! If you have the stealership fix those actuators,,,,, you better reload your check book with a LOT of cash!

Yes,, those actuators control whether the air moves across the cooling coil or the heat coil or a combination of both for temperate air.

You will NOT like the price for the repair!!!!!!

Its not that difficult to do the job yourself

shaob

on no!!!!! ok then. can you tell me if it's necessary to take that whole unit out of the dash to remove the actuators? or should I be able to take them off with just taking the top dash panel off? thanks so much
