I think I can solve that problem. First you have to tell me what year is your car. And what does the beep do... like if it beeps constantly while driving. Slowly or fast? Be specific about the beep.

Its a common problem in 90 to 93 Integras that the ICU go bad. Thats Integrated Control Unit. My car had that mysterious beep too. I did my research through other forums and asking several dealerships. ANd the majority said that the ICU solved their problem. Well, I swapped it with one that I snagged from the Junkyard, installed it and the sound dissappeared for 5 months now. Solved my intermentant wipers too.

The ICU controls the intermentant wipers, powerwindows, the defroster. If you want to know where the ICU is located Just email me and I'll give you more details.
