  1. Fuse #26 driver side ip fuse block. Labeled peps/hvac. Alternate Method (without Scan Tool) Note: Do not operate any HVAC controls while the HVAC control module is calibrating as this may interrupt the process. If interrupted, improper HVAC performance will result. Ignition OFF/ Vehicle OFF. Remove the HVAC control module fuse for a minimum of 10 s. Install the HVAC control module fuse. Start the vehicle. Wait 40 s for the HVAC control module to self-calibrate.
  2. What sensors. Also what's "upper and lower"
  3. How can one be a paid web programmer and make this mess. But I digress, You should have seen the GM corporate service and especially the training site. Cluster fck. They tried to update, wasted 2 years trying to fix it and gave up. Turned the clock and software back. Again, paid programmers. They make Windows ME look good.
  4. Paddle shifters? What the hell for? It's a truck. I put in drive and go. If I need to go faster, I push the throttle down.
  5. If it still smells ok, put it your truck. I do it every fall with left over mix.
  6. Depends what you mean by affordable. I would get a Tech 2. They run in the $250-300 range last I looked.
  7. Yea it would but don't be under the illusion that it will magically tell you what is wrong. It takes the tool, knowledge of how to use the tool, and probably a diagnostic tree. Maybe you can handle it, I don't know.
  8. My second shot was uneventful as was the first. Wife's second shot was pretty much identical to Grump's wife's experience.
  9. Again, these codes are o2 sensor heater codes only. Nothing to do with fuel trims or convertors. Strictly an electrical issue. Edit. P0154 is not a heater issue. The other 3 are. DTC P0154 HO2S Circuit Insufficient Activity Bank 2 Sensor 1 DTC P0050 HO2S Heater Control Circuit Bank 2 Sensor 1 DTC P0059 HO2S Heater Resistance Bank 2 Sensor 1 DTC P0155 HO2S Heater Performance Bank 2 Sensor 1 Without a p0430 code I'm not buying the bad convertor
