QuestionHi ted , I have a 93 toyota truck
signal lights flash fast and other lights in rear turn on too when head lights are on.. or brake applied
incorrect lights will light when brake applied if head lights on also when using signal ( all lights in rear come on some dimmer than others,
if key is off, and you turn on headlights and apply brake at same time , heater fan will come on and stay on until you turn off lights and release brake
they were all fine until i replaced head gasket.
I had replaced head gasket, negative side of battery was off for a week, I checked all connections i made after replacing head gasket seem good.. swapped flasher relay, headlight relay, rear light assemblys almost all bulbs, ect.. all fuses in main box and also box near driver side in cab are good...
This Gremlin is driving me nuts!. Help me please..ps i have a parts truck also.. so i can swap any parts you might think of , any wiring i may have disrupted to cause this?
AnswerSince everything was ok until the headgasket was replaced it would be safe to assume that the repair has something to do with the problem you are now having.
I'm trying to think just what that may be, it sounds like a wiring problem,the engine wire harness does not affect the lighting system, the part I'm concerned about is that the heater fan comes on when stepping on the brake, this sounds like a serious wiring problem, I don't think I can be of much more help here, if you'd like I can email a wiring diagram to you but I will need an email address.
One more thing I need to ask, does the engine start and run normally?
