Help with no radio no Heater issue.

92 Integra gs
200xxx miles

Hey guys. Yes, I’ve done my research and need help with figuring out how to fix it.

My radio and blower for the ac/heater only work on the first “I” on position. (refer to 1st pic attached)
When i turn to the second “II” on position,(refer to 2nd pic attached) both the radio and the blower turn off.

I’ve researched and decided to replaced a few items off a well working integra and still have this issue.

I replaced the blower heater relay (refer to 3rd pic attached)

I also replaced that 40amp fuse on top of all of the other fuses in fuse box in driver side. (refer to 4th pic attached).

And, I also replaced the ignition switch and still no go.

anything else it could be? I do have and alarm yet, i don’t think that could be it.

also when I’m driving I some times turn the key over to the first “I” on position until I hear a click. The radio and blower sometime work but for like a minute or so.

Thanks guys.

sorry guys. the pics didn’t load for some reason.

thats strange… best advice i can give is to double chesk ALL your fuses and make sure they are the correct size. also look for loose/bad grounds or pinched/cut wires…

other than that… i have no idea…

yup, alright.

Check for power on the yellow lead at the ign. switch harness, [acc. lead] it should have power when ign. switch is on I, [acc] and II. [run] but not in the III position, [start].

It still sounds like an ign. swithc problem.

Was that a new ign. switch you installed or a used one? 94

yellow one, okay. Ill do that. The ignition switch was indeed used, but works fine in other integra.

Thanks FCM.
