so if your defroster is having a problem that might be why your fogs dont work ---

thanks… I think I was hoping that someone else might have had a similar situation. I wish that I would have wired it to the fuse box instead of tapping into the defrost. ---

when i opened mine up, i noticed a lot of different things going on with the board. the capacitors were fine (no bulging, discoloring, or fluid emissions). i did notice some other things though. On D1 (the diode circled in red in the attached picture), the black insulation was broken off and causing it not to be insulated and flow current in both directions. luckily i had a spare ECU i have been using for parts (i chip ecus for obd1 hondas), and i desoldered a small diode of the same value to replace it. this fixed my problem with the oil pressure light coming on. it now only comes on before i start the car like it should. there was also another thing i noticed, the area around the three transistors (Q1,Q2, and Q3 i believe) was burnt and i could see a discharge around the base of the one i have circled in green. i desoldered this component in an attempt to replace it, however it has overheated and destroyed the writing on the back of it. i noticed there were two different transistors around it, one being a 1020, and the other i believe was a 2353? i put it back in since i didn’t know which one to use, however i would like to replace it since my rear defroster, headlight buzzer, and seatbelt indicator still do not function. if anybody could tell me what transistor i need to use for this piece it would make my life a lot easier. thanks! ---

Another ICU question Can I remove the ICU and still drive my car? I was unable to clearly define the burned track by my cap, I want to take it to work to repair it. My TEG is a daily driver. ---

it works. it all depends on how badly the cap corroded the paths. my defroster would mess around a lot prior to this and my intermittent wipers didnt work. The defroster problem was fixed but the intermittent wipers still dont work. i believe its cause of the broken paths. ---

i dont have any leakage under that capacitor thats posted in the pic, i have leakage and corrosion under the one labeled C8 i believe. its in the top right corner if you’re looking at that 1st pic in the thread. any thoughts? i do have symptoms, such as no int. wipers, seatbelt beebs, sometimes oil light comes on but its dim… [Previous page](https://forum.g2ic.com/t/how-to-fix-the-icu-for-less-than-5/64231.md?page=1) [Next page](https://forum.g2ic.com/t/how-to-fix-the-icu-for-less-than-5/64231.md?page=3)
