  1. They could put it in the system and see if GM will give you any assistance on it. But 100% coverage is a thing of the past. It's normally like 70/30
  2. My 85 has everything factory but the compressor. When I changed the motor to a 383 I updated the ac compressor and retrofit the 134.
  3. See above post. Edit If you go to the 7:37 min part of this video you can see the tape on the right side of the condenser where I am installing it.
  4. I am a GM Tech. Lol. The problem with the condensers is the weld. The heat from the transmission causes thermal cycling on the combination transmission fluid/oil and AC condenser cooler creates a crack. The tape... Lol Just as you guessed is... (drum roll) THERMAL TAPE! What it does is transfer the heat from the weld and doesn't allow it to crack. (even though I have replaced the one's with tape leaking in the same place.) Hope this helps.
  5. You're right. I don't deal with it everyday. I don't know why I thought I knew what I was talking about. Well, Enjoy working on your street rods. It really is a lot of fun.
  6. Well I own a GM Dealership. It's a family business and I have worked in the Service department since I was old enough to turn a wench. I have been the Shop foreman for the last 20 years. You may have purchased an extended warranty from an aftermarket company or even a GMPP warranty and had many of repairs done under warranty. But getting GM to give you any warranty repair other than the one time good will... Will never happen. There could be a special coverage (like the one you have on the Tahoe's and Yukon's for the condenser's) But you only get one good will warranty repair. I have many of Street rods myself. Including the one in my profile picture which is my every day driver. Currently building a 1958 corvette and I have a 1918 Buick in the show room that I completely restored. If you would rather wrench on a street rod and spend hours of your time negotiating in the hopes of a repair instead of wrenching on your every day vehicle for an hour... Your time must not be that valuable. Again, My suggestion is only an option. Not forcing you or anyone else to do anything your uncomfortable doing.
  7. Sure. Go ahead and negotiate. They will happily use your one time good will on a ac condenser job. But when you're steering module, your HMI, or something that actually requires a part that costs over $1000 and you call to try to negotiate... When they tell you, "Sorry, we already gave you assistance before..." You can fork out the $2800 it cost to replace the steering gear. Extended warranty is also really nice. You have a Minimum $100 deductible and if you don't have a deductible you paid way more than the cost of the job in the first place. But to each their own. I'm just pointing out that you can do this yourself and save yourself a lot of hassle. Then again, some people are better negotiators than repair men as well. Just throwing out other options.
  8. You shouldn't have any issue! It's a simple repair.
  9. You need to pull the codes. It will probably be a random misfire code. The good thing about taking it to a GM dealer and having the codes ran is the tech will be able to see the exact misfiring cylinder in the misfire data. This can help lead you to the failure. If I had to guess. A 2015 with 59k miles on it. I would bet on a injector with low flow. It still could be as easy as a spark plug wire that is failing under a load though. It really needs some diagnosing to find out for sure and an Indy shop isn't going to have the proper scantool to show the misfire history unless it is a top rated shop and has spent a lot on scanning equipment like GDS2 and will probably charge you a premium to test where it would be just as costly to take it to the dealership. I did a whole spill about Injector drops on these vehicles. We are seeing more and more of them in these direct injection engines. Here is where I explain the 50d code which is kinda what I am tell you about above.
  10. You can literally do this job yourself, under an hour for less than $300. I could understand if GM had this huge engine related failure where the truck was a complete loss unless you had extensive Mechanical knowledge. But it's not. You could literally do it with your girls box of tools. Lol. Also, It's the air conditioning. Nothing that's going to prevent the vehicle from running. $300 and one year of middle school shop class and you can do this job. And $300 is expensive. $120 condenser - https://amzn.to/2K10zH0 Ac System service to charge system to 1.32lbs - $75 - $100 $100 to buy any tools you don't have. 1 hour of your time. And watch this video.
  11. You wont be able to see a problem inside the actuator itself. It has the wrong resistance value for the counts. The actuator from GM is $275 plus tax. The labor would be around 1hr. So probably $400 to fix.
  12. The drivers side actuator is located on the passenger side floorboard. Here is a video of the replacement.
  13. Ok, So we all know AFM lifters have been known to have issue and I have seen a lot of people post tricks, or preventative maintenance, or the most farfetched information I have ever seen in my life explaining why they tend to go bad. So, With that being said. I thought I would give my view on what I have been seeing and what is causing the lifters to fail. The first thing and most important thing is… MAINTNANCE! If you fail to service your truck like you should, you will definitely have an issue. I would really recommend not using the oil life monitor and changing your oil every 4000-5000 miles. You can use Synthetic or non-synthetic oil if you follow this schedule. Oil has come so far from 10 years ago that regular oil is not that different (as far as breakdown and effectiveness) than synthetic oil. The AFM activation and deactivation is controlled by the VLOM (valve lifter oil manifold). It has 4 solenoids that direct the flow of pressurized oil to the AFM lifter when controlled by the ECM. Now this is why changing your oil is key. The filter underneath the oil pressure sensor controls contamination from clogging AFM lifter. If the filter gets clogged from trashy oil it will cause low flow to the AFM lifter and cause it to fail. The amount of pressure the AFM lifters need to operate is 25-65 PSI of oil pressure. It needs 22 PSI of pressure to unlock the pin releasing the Lifter. This is why proper maintenance is critical. That’s the main cause of the lifters failing, even though many other things can cause it. Modifying your ride height of the truck can cause an over activation issue. Poor fuel quality will cause the same. Larger tires causing engine strain causing over activation and the obvious… Faulty parts. Everything is man made and prone to fail at some point. Just wanted to put my 2 cents out there. I will also link a video to the removal procedure for replacing the AFM lifter. I am working on another video for the installation now. I hope this information is informative and helps someone!!
