My Acura 3.2L TL a/c does not turn on. Neither does fan even when a/c is OFF- I have checked fuses INSIDE car. Whenever I pull fuse out and reinstall it, I heard A/C system turn on under the hood, with no fan action in car; but in 5 seconds, it all turns off. I notice inside engine compartment is another set of fuses. The largest fuse box has descriptions of fuses and relays in it. I have checked any fuse related to A/C and switched out the Condenser Fan relay and Cooling Fan relay. No luck. I really don't know what to look for. I also notice 2 other smaller fuse boxes under hood. One far left, one far right. Both have some kind of relay in them that are all identical to the Condenser Fan and Cooling Fan relays. But they are not marked so I have no idea what they go to. Car has gps screen so I did the Self Diagnostic test. Code of blinking 88 comes up along with one that looks like: an capital "L" lying on it back and a "1" lying on its back. So far what can you tell me?

Check things in pic underhood first then get it scanned as it's auto temp control.

What do you mean "get it scanned"? I already did a self diagnostic test and it gave me a code as to what it is; so I am hoping someone can tell me what that code means as described in my initial question box. But for now I am running to store to check the 3 items you showed with arrow-the 40A and 20A fuses, with the Blower Motor relay.

The codes that ae displayed are alphabetical a through n. However your says it's like an l lying on it's back. There are some pcm problems related to grounds so the only thing I can suggest is to check the pcm ground to the relays. Hence it doesn't send the ground to the relays and the scanner will say it's a bad control head when actually it's the pcm ceasing the problem. Honda doesn't even list this so it makes it fun for us to find the true problem. Because your control head isn't reading correctly this may be the cause so get it scanned anyhow and or you can try cleaning the ground on the back of lh cylinder head as it is a common ground for hvac. You might also try cleaning the ground for the blower relay which is at the lower right rear of engine compartment.

I notice pic you sent me of fuse box. Does not match my pic of fuse box arrangement. I will send you what I see and maybe you can re-direct me as to what fuses and relay to replace.

Thanks, but which one is 56 fuse? I dont see a 56 on the fuse box cover. I only see written description of fuse and its amperage. You also said this car is a type S? Believe me, it is a 2003 Acura TL 3.2 -4 door
