my truck has been acting funny underload after it warms up for awhile now, and i finally found out what it was.

it's called the "circuit opening relay", and is located under the dash, near the pcm on the passengers side.

i tried to get the best pics i could. hope this helps somebody else out.





the part is $95 from toyota

 

hey I know right where that's at; I was in there yesterday installing my glove box light

I might have to unbolt mine and pop the top off just to have a look


that looks nastey like water got in it or something

 

becareful when you pop the cover off, mine cracked and crumbled. you can't really see it in the picture, but the whole side where my thumb is is gone

i don't know how it got so rotted. i've never had water in the cab. and i bought the truck off an old guy. when i bought the truck i asked if the 4wd worked, he said "i don't know, i've never used it" which leads me to belive he never had water in the cab either

 

It's called "old age".
