First off, I have to say, I have been looking @ this site for a few days & it has been very VERY informative and helped me learn a few things.. I bought my 2004 GMC Envoy used almost 3 years ago, and have had nothing but problems with it, it seems. The only instrument on my dash that works is my gas gauge, and it's not always right. My speedometer stays at zero, my temp gauge is in the black area, but the most important, is my A/C only runs cold on the driver side. The passenger and rear blows super HOT! Now it's in the middle of summer here in Arizona, and I just can't bear it anymore. I have read up on this site, about the mode actuator being replaced.. and I have thought about doing that..but then I went to Autozone today ( since my check engine light is on) and these are the codes that came up

P0455 (EVAP LEAK "Large")

P0410 (2nd Air Injec)

P0014 (Cam Pos Actuator B)

I know my gas cap is loose, and needs to be replaced. So if any of those codes have something to do with that, then I'm almost positive that's the problem.

If anyone can give me any insight to what is going on with my car, it would be greatly GREATLY appreciated. My husband is currently deployed to Iraq, and usually does the maintenance on our cars, So I'm really not sure where to start.. If I knew what was wrong with the vehicle, and it could be fixed at home, I can do it, to save the $.

Any help would be appreciated, or links to other threads regarding these issues to point me in the right direction would be a big help!!
:thx

So, while attemtping to go look at how to replace the mode actuator, I'm a bit confused.. Mostly at how am I supposed to remove the lower dash covers? Isn't that quite a bit of work? I'm awfully scared to tackle sometime like that. :undecided
