How do u work the defrost?

I have a 91 rs integra my defrost button doesnt seem to click in, i thought it was the switch on other da integras its all the same. I also checked the fuse also.

it doesnt click and stay in, when you press it the little orange light should come on, when your rear window is fogged up press it once to turn it on, if it defrosts its working fine, if not might have a problem with your ICU its a common issue and you may just need to replace a capacitor in the ICU or you may need a new one if its too deteriorated

do your intermittent wipers work if not its your icu.

well thats not a guarantee, cause some people have a huge range of problems, my defrost works but the actual defrost on the hatch is messed up yet my intermittent work intermittently when they feel like it, i got a new icu just need some decent weather to tear into the fuse box.

thanks i’ll check the icu

intermitently working intermmitent wipers is a sine of the icu and sorry what i meant was if you have this plus when you press the button nothing happens its a good chance its the icuanother indicator is a weird door chime noise that comes and goes off…:rockon:
