Is there any reason striaght piping an '06 would cause the A/C to act goofy? A friend of mine just did his exhaust and now the A/C is not working. I'm thinking coincidence.

well tell your buddy to get it to the dealer. im not an expert by any means, but i dont see how there is anyway to link those two together??? hopefully he has a good dealer and his truck wont come back worse than when he took it in!!

brett

 

Dealers are evil, they will charge you an arm and a leg for nothing...what is the A/C doing/not doing?

 

My thoughts EXACTLY!!

 

Only thing I can think of is if a MIG or TIG welder was used without isolating the PCM.....????

 

2nd that idea.. If he used a welder and did not disconnect both negatives off the battery he might have fried something.

 

egggggg-zactly, please always disconnect your batteries before you weld on vehicles.

 

My guess would be the recirculation door problem...just a coincidence. My 06 broke a week ago. The blower started making a funny noise so I opened it up and took the broken door out.Took it to the shop and they had to pull the dash and replace the whole assembly... I think. It works fine now.

 

I had a brain fart and did some welding on my cousins truck,when we got done nothing worked because the pcu was fryed. Wegot in a hurry and didn't take the battery cables off,like I have allways done before. Big exspensive mistake.

 

Didnt have any problems on mine, straight piped my 05 the other day, welded in some pipe, started up just fine, no a/c issues....
Now I probably should have disconnected the cables just to be safe, but forgot about it....

 

You got lucky. Alot of people dont think to put the ground as close to the work as possible, especially on today cars/trucks/heavy equipment ect.... Even after disconnecting the batterys ( which is a must ).

Quick story, About a month ago I stopped up a friends shop that I hadnt seen in a while. He had a new ford king ranch in the shop and installing a gooseneck in the bed . The guy working on the truck was new and pretty much out of tech school. While were sitting there b.sn the kid comes over to him and says Im done but the truck wont start. He goes over to inspect his work ( nice job I might add) and goes to try to start it himself. Nothing. Pops the hood latch gets out of the truck walks to the front and trips over the ground clamp that was attached to the front bumper ( he was working in the bed ). And thats where all hell broke loose, the kid almost (should of) lost his job, and my buddy was out $3000. Although he did have the batterys disconnected. the distance was to far. The current will always take the path of least resistance, and in this case, somehow, it was the trucks brain.

 

Had the ground clamp on the tail pipe, but I will be safer from now on
Sounds like that really stunk!

 

When I was 19, I welded on a mixer w/o grounding properly - every amp went right through the motor windings on the way to the electrode... wow, I couldn't believe armored cable could glow that bright!

Must have left some varnish on the windings, cause it ran OK afterward - but I sure learned my lesson...

 

Since the A/C compressor is so close to the exhaust or turbo is it possible that the harness became disconnected or damaged?
