1) The Horn.
I don't know "why" it is, but every used Toyota I've owned has ended up with a horn issue. The first was a 1982 model. The horn problem with that truck turned out to be in the steering wheel. The contact ring in the hub was boogered up and had to be replaced. HOWEVER the Tacoma is another deal all together!

My 1995 Tacoma has developed a problem - within the past year - where the freaking horn works when it
wants to! Usually when it's above say 48 degrees the crazy thing
won't work. But... when the temperature goes below 48 degrees - the colder the better it seems - the damned thing
seems work every time?!
So, I've asked around and I've been told it's probably the horn itself. Problem is... I CAN'T
FIND THE DAMN THING to check it out! Does anyone know "where" the hell the freaking horn is on the early model Tacomas (i.e. 1995-1999)?! It's a stupid question I know, but in all honesty I cannot find the f-ing thing!
Ok on to...
2) E-Brake Light.
My emergency brake light literally
stays on! ESPECIALLY when it’s good and cold outside! The
exact opposite of the freaking horn! Go figure.

In any case, I know the E-brake isn't engaged, because it's the old hand-pull lever type under the dash. However the light stays on! Every now-and-then I can make a turn - to the left or right - and the light will go out momentarily, but once I make the turn it's back on again, which further tells me the E-brake isn't engaged.
I think I know what the issue is here. I think it's just the mechanical solenoid/sensor - which I "assume" is located somewhere on the rear brake drum - and it's just sticking. I'm hopeful a little bit of lubricant will fix this problem, but I won't ever know - because I have NO idea what I'm looking for! No idea what that solenoid/senor even "looks" like.
So that said - once again - can anyone tell the "exact" location of that sensor and what I need to be
looking for to ensure I find the "right" thing?
As always guys.... MANY THANKS in advance.
