The issue is with #16 for me. Maybe it’s not as difficult to replace it as the others are.

On my 1997 Silverado, my A/C suddenly stopped blowing cold. Mechanic checked for leaks, none found. After checking, i started hearing various noises inside the cab near the blower motor, after further listening and inspection it appears I have a bad actuator (or whatever the piece is that is right next to the blower motor portion). Is there a specific part number that I need to look for to replace it? Thanks, Brandon

Update: After investigating multiple issues, it was determined that the fuel injectors were bad, distributor cap and rotor were also bad, and had a minor coolant leak. Fuel filter was also replaced. Those have been fixed/replaced. My trucks seems to be much better now

Sadly, I replaced my coil....issue still there. The mechanic that gave me the advice looked into the problem further and he suspects a bad fuel injector as the truck only does this at certain load and when the engine is wanting more fuel....Gonna try some fuel treatment to see if the injector is stuck....if the problem persists.....it will be new injectors and pressure regulator. Seems to be a common issue on these engines

I'm having the same problem with my 97 5.7L, and a reliable mechanic told me to check the ignition coil. Sure enough it is cracked and I can see where it has been cross-arcing. I have new parts from ACdelco on hand, just trying to find time to replace it and see if that improves things.

Mine is having similar issues, but has actually given code P0300

A mechanic friend of mine is thinking the torque converter is bad

Just to give an update on the issue: I have not had enough time to inspect the U-joints yet, still planning to do so. But yesterday I had to make a trip in the truck to another town located in the foothills of the mountains near me and the 4 - lane has some steep incline in portions and the truck shook violently when I had to give it more gas for the inclined places to maintain speed limit drive. RPMs were between 2000-2300 at the time of the shaking. The only way for me to duplicate the issue is to get the truck on an incline. Flat roads don't appear to be much of an issue.

My initial thought was the U-joints. I will check those and circle back with results. Thanks

I had it aligned when the new tires we mounted about 2 weeks ago. Tire shop is trustworthy and the alignment shop is as well.

I bought my '97 Silverado from the original owner a few weeks ago. 149k miles on it when i purchased. It needed some attention after purchase such as: New tires, new belt tensioner, new pitman arm, new sway bar links, new Valve Body in Trans, new A/C system O-rings, But my issue is at 40-45 mph and 65-70 mph, the truck will shake badly until I accelerate or decelerate to a different speed. And yes the wheels and tires are balanced correctly as far as I know. the truck itself drives great until you get to these speeds. I notice it the most driving through local towns as the speed limits are either 35 & 45mph. I notice the higher speed issue on the 4 lanes I travel on from time to time. Could this just be fault U joints? I do hear a noticeable "pop" when I put the truck in gear when I begin my trip to work ,etc. Just want to track down the cause and have this truck driving as nice as it looks. Any input and advice is appreciated, -Brandon

Do you know where to find the ground wire locations?

I've never had a problem with other vehicles.
