I've been noticing recently that my a/c compressor doesn't seem to engage until 30 seconds or a minute after turning the a/c on. Ambient air temps in the low 80s. I get in the truck, start engine, roll down windows, wait about 30 seconds, begin driving, roll up windows after a minute, then start a/c. Once the a/c does decide to work, it's ice cold within a couple seconds. I've not verified if the compressor is actually engaging, yet. I've also not ruled out a blend air door issue. Is this normal operation?

 

There is a TSB on the compressors for that year. It should of been done prior to you purchasing it from the dealer, but I would call and check.

 

This is exactly how my 2024 works. Not sure if its normal but its annoying.

 

I remember reading about this a while back. Is this the TSB you're referring to --> https://static.nhtsa.gov/odi/tsbs/20...16357-0001.pdf

 

Agree, it is annoying. Even the HVAC cabin air fan on this truck has a delay. There's like a 5 to 10 second delay between turning the fan **** on and the fan actually turning on.

 

My '25 F250, with a May '25 build date, has these same delays. It's been checked by the dealership and passed whatever the TSB's requirements are.

 

I also get it on my 23 from time to time as well.

 

Same for my 25 250 may build.

 

My '24 has climate control. It does the same thing. I actually think it is a design feature, to let the engine stabilize RPM before adding the load of the A/C compressor. It seems to correlate with the RPM dropping from around 1200 at startup down to around 900. I always wait for that RPM drop before engaging the transmission. Less lunge when it drops into gear.

Come on now, you really can't wait 30 seconds for A/C? Just leave your door open for half a minute.
