tried the posted threads, nothing was there. Dealer is wanting 200 for part plus labor to fix this code. OReilly says part is dealer only. I see where some have fixed this problem.... my truck is 05 silverado, 1500, 2wd. any help?

Yes its possible the part is Dealer only as it is an emissions part, guess they have to keep track of how many of there EPA required parts fail maybe?

jvtexas I got your PM and will see what I can find this evening....

I have just experienced the same problem with my 06 silverado 1500 with 60,000 miles. This being such a big problem you would think Chevy would would have a re-call of sorts. That being said I have been quoted $153 for the part. I understand that the same part is on an 06 Suburban; same part # 25932571 as old part # on truck. I havn't replaced it yet but for $28 will give it a try.

I have done 2 more trucks with one being all ready done by dealer and the valve failed again so the old valve part fits perfect as a in with the new conversion the dealer will do.
Also just found out what has been rattling on all my past and present Chevy trucks.It is the white looking spacer on the bottom part of the steering column put a dab of silicone on it and it works great.

Ghost,
Where did you get your solenoid for $28? Also the pics you mentioned, is there a link to them or what?
Thanks,

Just for clarification. The relocation kit from GM is about 150 bucks for the vent solenoid not the purge solenoid. Code p0449 is more than likely the vent solenoid gone bad. Hence the engineering change GM has made. You can buy the solenoid itself for around 20 bucks and takes about 10 mins to change. You will have troue finding just the solenoid BC the dealer wants you to buy the relocation kit. Tomorrow I will try to post the part number for just the solenoid, because that's how I got the part. The local AC delco dealer didn't have the part number in their computer. I know thisis an old thread buti just wanted to add the info I couldn't find while I was doing my search.
