I've got a 2005 silverado 1500 5.3L crew cab LS. Just wanted to let anyone know who is having a popping noise of some sort inside the cab that sounds like it's coming from the AC vent area under the dash but behind the ash tray or glove box. That general area, hard to say exactly. The noise is really annoying and sounds like something is loose withe the vent or dash itself.
 
Just back back from the chevy dealer and they fixed it so far anyway. It's a D4707 Module or assembly, hvac control head reprogram that was needed according to their receipt. Further explanation is 3L A/C actuators out of calibration, left temp clicking -Chk A/C data with tech 2 and recalibrate A/C controls actuator ok at this time. 0.4 hrs.
 
I searched on the internet and apparently other cars not just GM uses this type of programmable actuator/controller for the AC. Must have been a tolerance issue wiht the software.
 
The silverado has about 4200 miles on it. Bought in april 05.
 
Best gas mileage I've seen is about 19mpg although the sticker says 20 is the highway mileage. Most of the time it is 16 or 17 for around town.
 
I tow a 23 ft twin outboard offshore boat, twin axle trailer. Probably over 5,000 lbs No problems there. I like the suspension a lot better than the smooth ride suspension on the 4.8 L truck but I still think the suspension could be firmer with better shocks and springs.
 
I know the difference considering I drove an 02 vette with the z51 suspension package for 1.5 yrs. I don't think there's a better suspension out there. The truck is a bit too soft although the HD suspension in the crew cab is better than the smooth ride suspension. I still believe it could use improvement particularly if you tow anything. Occasionally the truck can get into a harmonic when towing on the front suspension that causes the nose to bounce going over hills. Not what I would prefer. Stronger dampening rates and springs would probably help a lot.
 
Anyone know of any after market stuff to help out the bouncy-ness of the 1500 suspension (I've got the heavy duty suspension but not the HD truck).

I purchased an 05 Crew Cab LS this April, I have had problems with the front-end suspension as well. The A/C has not had a clicking sound but rather a gurgle that is constant. "GM" said the gurgle is normal. ??? the bouncing of the front end on bridges is with or without a trailer. I have also noticed that the front end has a "jolting" feeling over "any" irregularity in the road. I drove an 04 Crew Cab from East Texas to Wisconsin & back last year and never noticed anything close to this action. It drives more like a 60s model 5 ton front-end not a $30K, 1/2 ton truck. After the dealer tried to fix another like truck with the same problem (with no improvement) GM called and told me this is normal for this truck & "Your Case is closed" !

My 05 Crew Cab truck has front suspension problems and A/C problems. GM refuses to fix it. I have filed with the BBB but they are very limited in what they can do to help. Everyone needs to speak up if they have a problem. GM has a really bad attitude They just told me "to bad" . what is the number for the CEO?

I too have the AC problem. 2005 Crew Cab LS Z71 5.3 V8. It is a constant hissing/gurgling and is easier heard when the AC is at 1 or 2. The sound continues for some time after turning AC off and even after the engine is turned off. I have heard similar sounds in other vehicles, but this is very noticable and loud. I've had people ask what was wrong because it was so annoying. Usually I just turn up the radio or the AC to 3 or 4 and I can drown the noise out. Other than that, I love the truck. It rides great--no suspension problems. Added a flowmaster and opened up some of the restricted horses. Sounds great and better mileage!
