Sup Aaron...
Of course check the basic things; blinker fluid, muffler bearings, boost fluid, knuzitzs rod savers... You may have incompatible USDM voltage on a JDM only aftermarket lights.
Unfortunately without phyically seeing the setup I can only tell you to check for bad/croded crimps/splices/wires/bulbs/fuses etc... If there is a relay (there should be) the coil/contacts may be bad.
If you can chop a switch,trim, & some of the wires that go with the switch out of a "junk" car we can retro fit it in & make it look factory...
If you want a hidden switch or just make the darn things work period, that is doable.
As far as bringing it up or me coming down... Hmmmmm
If you do decide to stop up we can fix it, & hang for a while...
Saturday is bad & there may be time on Sunday...
