JDM H22 Swap - Only 2 Problems - Honda Prelude Forum

07-10-2006, 08:17 PM

Well, me and 2 friends did a JDM swap last night. It works flawlessly other then a few problems. One, even if the car has been off for a long time, and you start it for 10 seconds, the radiator fan will be on afterwards for 10+ minutes. The other problem is the headlights don't work. Now, when I turn the headlight switch on, the gauge lights/etc come on, and they dim, but the headlights don't come on at all. Also the amber corner/parking lights work as well.

Prolly simple stupid fixes, just need to know because I wanna drive this thing! So quick answers would be great!

Ok, for the knock sensor, the jdm h22 doesnt have it. The o2 problem is bad wiring. The fan problem isnt the switch on the distibutor, but I have bigger problems. The headlights still don't work. It is very odd. I had them working, and then they stopped. I moved the wires with my foot, they worked for a second, and stopped again. I had to drive home from work with no lights. Now I see that the passenger side corner light comes on but the other corner light, or either of the headies don't. Now, I have jdms that shoulda been here last friday, so I don't wanna buy new bulbs, although they look fine. I dunno. strange problem. Other then the fuses in the fuse box, are there any fuses that are connected with the lights?

Any help would kick a$$! I wanna drive my new engined car @ night lol....

Mine went out a few times for a few hrs at night randomly. i pulled over and was tapping the headlight n **** then i tapped the fusebox in the engine bay cuz i was getting pissed and they turned on. I dunno what it was but it worked! try it and see if it helps you.
