AC condensation runs over Transmission/Exhaust

[TKeslar]

I just added a Borla Touring exhaust. I was running my AC for the first time this year and heard a sound when I stopped that sounded like water dripping on something hot. At first I thought it was due to the exhaust, but then I found this thread…

Has anyone experienced this?

I haven't heard it, but have observed it.

I'm getting some AC condensate in my ducts and occasionally it smells bad. Haven't seen that in my last couple of GM trucks.

I have heard it. Whats the big deal?

As I mentioned, I just had a new exhaust put on the day I noticed it. I just wanted to be sure it was not due to the work I had done. I was curious if anyone else had experienced this. I’ve never owned a vehicle that did this.

I live in Vegas and run my air CONSTANTLY and have never heard or noticed anything like that. I will pay closer attention

Now you’ll never unhear it.

My new 23 ZR2 does it.

 

[securityguy]

Been driving my truck for 6 months and never heard it or smelled anything.

Mine does it. I can hear a sizzle under the truck after driving.

Mine does it, never bothered me?!

Yes - just added the Touring to my 2022 Trail Boss... tzzzz tzzzz tzzzz is what I hear everytime I get out of the truck after having run the AC. This sucks, and I'm going to try to rig something up under the drip pan to divert the water a couple inches. Some guys on hear have said 'what's the problem'... the problem is that cold water dripping on to burning hot metal is going to fatigue the metal and turn it into a hole after time (stainless or not).

Witness the sizzle

Witness the sizzle

That's like every raindrop in Arizona.

Hard to believe this is by design. Has anyone successfully diverted the drainage?

LOL--they have been doing it since at least 2020. My 2020 did it and so does my 2024.

Yep my 2020 done it the whole time I had it and never caused any issues . Have heard my 24 do it a few times as well.
