My 2007 classic silverado stopped blowing cold air yesterday. Worked fine until we stopped and got back in it, then would not blow cold air. I listen for the compressor to kick in and could not hear it. If it is the compressor how much am I looking at in cost?

A compressor change won't be cheap since your system would have to be evacuated and then recharged afterwards. You could have something as simple as a pressure switch causing you problems. Take the plug off the switch and jumper it to see if the compressor kicks on. If it does change the switch. If it still doesn't cool then have the refrigerant checked.

The easy fix is to get one of those 134a cans with the gage. They run about $20 at autopartsland. Attach it to the LOW side (the only place it will fit) and follow the directions. If that does not work, go to a pro...

      OCI, not when but why?

      By KARNUT · Posted

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case." The American Heritage® Dictionary of the English Language, 5th Edition • More at Wordnik   If you'd like to disagree call your Senator or Representative and let him know his departments are in error. But you and I? We are not doing this.

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.
