The Truck: 03 Chevy Silverado 1500 4.8 V8

I have a kind of squeaking sound coming from my dash. Here are the facts of the noise

It squeaks in park and drive, idle and moving

It doesn’t squeak unless the defroster is on

When I switch it to AC it turns into a clicking sound.

The heater does not get very hot and the ac does not get very cold. However, when I purchased the truck back in September both worked fine.

I figure the problem is in the AC system but I do not know what needs to be replaced. Any suggestions?

I tried to attach a video of the squeaking sound, hopefully it will play correctly. The video was taken while in with the phone sitting on top of the drivers side dash

  //// Luckily here also--I have a ;local independent shop that will service my vehicle with my supplied fluids. I'm to old to lay on the ground and do it anymore. The m Shop owner and his Son have been friends for years and we were both in the towing business for many years. it's good to have support when you need it. glenn

  To last poster there in Wilmington, NC--Not too far from our place at Atlantic Beach...what is referred to as "Southern OBX>> I am a little sad as life goes on that we never actually moved there when we first visited-44 years ago. Love that beach area-even though I don't move around as quick as I used to- glenn

  LM2 and LZ0 DO NOT have a thermostat in the valve body. LM2 and LZ0 still have the water to oil heat exchanger that the ATF goes through no matter what. So if the thermal bypass in the lines to the aux cooler is closed, ATF goes out the transmission, into the water to oil exchanger, to the thermostat and then back to the transmission. When it gets hot enough to open the TBV in the line, it will then flow to the aux cooler out front to regulate temperatures. The cooling system is going to warm the ATF up as the exchanger is part of that entire Active Thermal Management cooling system. LM2 and LZ0 DO NOT have a thermostat in the valve body. Just the one in the lines. Stock TBV opens at 194F. From TSB 22-NA-182 10 Speed (10L80, 10L90, 10L1000) - 143F (61C) - TBV is within the valve body on all listed applications except those equipped with 3.0 (LM2) (LZ0) Diesel. The (LM2) and (LZ0) Diesel, the TBV is on the frame rail, external to the transmission and opens at 194F (90C). As for your big Duramax, the transmission cooler lines still flow through the side tank on the radiator, so deleting the TBV in the valve body will only lower it so much.

  Installed the PPE bypass on the RST last week. With ambient temps between 75-95, the trans temp dropped from 195-198 unloaded to between 180-185. Not what I was expecting (also has the Max Trailering package). I have a Nextgen diesel valve body upgrade kit going in this week and the remaining thermostat in the pressure regulator valve will be removed and I'll see what happens. I did the same mod in the Valve body upgrade kit for my '24 3500 HD Duramax and I haven't seen much difference in trans temp but I've just been running back and forth to town so far.

  It's going to last a long time. You seem to take care of your vehicles and that is key. I wish I kept my 2002 Silverado. These new vehicles are not built with quality anymore.
