I recently picked up a 97 Prelude SH and I'm having an issue with the AC. It blows cold as hell when you're stopped, or the RPM's are anywhere below 2000. As the RPM's get higher, the air gets warmer. The fan doesn't slow down any, the air still comes out at the same speed, it's just warm. I don't think any of the major AC components are messed up. Could a belt be slipping? Or is it an sensor?

You can rule out the belt slipping. That just wouldn't make sense. If the engine is spinning faster, why would the ac spin slower than at idle?

 

Cause if it's spinning faster, it can't grip as well?

 

Ok, that would mean a little slippage. But not enough to slow it down below idle speed.

 

The rate at which the air is coming out remains constant. Temperature is what is changing.

 

just be glad you ac works at all.

I am not sure about the preludes but there are some cars that disengage the A/C clutch for better accleration. Maybe that?????????

 

Don't think so. It's when I'm just cruising.

 

automotive air conditioning systems frequently FAIL. Might be time for a charge with some dye in it to find leaks.
