Hi everyone, I have a 89 CRX Dx and am having an annoying problem with the door ajar buzzer. It should be noted that the seatbelt indicator light works every time, as does the door ajar. Neither light up when they shouldnt. But I do get the "beep......beep.......beep......beep" while driving. That would make me think problems with the door switches. But does the hatch also activate the beeper ???


Ideas ???

What switches control the beeper ???

 

I used to get it, turned out to be my door. I adjusted the striker to be in a bit more and it solved it. My only conclusion is that it just wasn't aligned enough to fully close that circuit even though the door technically was fully shut. I discovered that when I leaned on the door the beeping came on but turned off as soon as I tugged the door inward. Hope your fix is as easy as that.

 

disconnected the door switches and still get the beep. Also radio goes out every now and then. Thinking I must have a short to ground somewhere along the wires that can close the circuit for the beeper. . I am going to disconnect the door connector to rule out any wiring in the door , but thats unlikely.

 

After searching and reading I conclude it must be the ICU. Ive been working on vintage circuit boards for the last 6 years , these use all through hole components and should be very easy to repair. I plan to replace all the capacitors and any blown transistors on this board, as well as repair any burnt traces and resolder the header pins...It should work , And if it does I will be offering repairs on these for $25.
