I would encourage you to take your vehicle to your local GM dealership to be looked at. Please keep us posted when this has been taken care of.

it could be an exhaust leak, also the inlet and outlet tubes to the EGR could be clogged, also improper set of the EGR gasket.
in addition, you can check:
Check for the following conditions:
Important: Remove any debris from the connector surfaces before servicing a component. Inspect the connector gaskets when diagnosing or replacing a component. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion.
Poor terminal connection. Inspect the harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and faulty terminal to wire connection. Use a corresponding mating terminal to test for proper tension. Refer to Diagrams.
Damaged harness. Inspect the wiring harness for damage. if the harness appears to be OK, observe the sensor display on the scan tool while moving connectors and wiring harnesses related to the sensor. A change in the sensor display may indicate the location of the fault.
Inspect the PCM and the engine grounds for clean and secure connections.

Its a rheostat for the fan switch that is located below the glove box near where the floor and the firewall meet...I found the exact location by using the autozone website parts location search tool...the rheostat was like $6.00 but it was a little difficcult to get at...small 7mm screws in a tight spot ...but do-able. The loss of the lower speeds on the fan switch is a typical indication of the rheostat failure.

Only hot air comes out when I have my A/C on. We tried to recharge my A/C and it only fixed the passenger side A/C. Can anyone help me please. I've been dying all summer. I have a 99 Buick century

Hi, I broke off the plastic two-piece unit (two-cup holder & change dispenser) that folds inside the compartment between the front driver's & passenger's seat a while ago. I'd like to reattach it. There doesn't seem to be any missing or cracked parts. How would I do this? I visually various ways to line up the parts, but can't figure it out.

Mine also had that problem. When I told the mechanic that I had a coolant leak and couldn't find it, he knew right away what it was. Mine was both the external and the internal gaskets. Car had 154,000 miles on it when they were replaced and cost almost $800.00. Unfortunately the lawsuit had ended when mine happened. But on a good note, the mechanic said it will last a long time now with the new ones.

Your not fully charged. The label is incorrect, add .5 lb. Right now you are only using 1/2 the evaparator. This was a common issue and unless you were an A/C tech for GM you wouldn't know. I was so I do, LOL.
