Has anyone encountered a problem where there headlights dim to varying degrees at random? Also the blower motor blows stronger and weaker with the lights. So when the lights dim a little the blower motor slows down a little, when they dim a lot the blower motor is barely running. It doesnt effect they way the car runs, idles or drives. Any insight would be greatly appreciated...

lately since i,ve been driving my sc250 im getting a strange problem with my brake lights and my dash lights . when i step on my brake my right side tails park lights cuts out and the cluster light blinks .i cheacked all the grounding points and they seem to be ok .anybody have and idea what is making my lights go crazy

 

I think you both have bad grounds.

Yours sounds like it is a problem in the tail light harness though.

 

Exactly what I was going to say.

 

well yesterday i checked all my grounds so im guessing it is the harness .hopefully i can find one in the junk yard ,thanks fellas

 

I am actually having a very similar problem with my sc as of about a week ago. when I am driving, intermittently and only at random will my lights/dash/everything electrical come close to cutting out. In fact, one time the entire car turned off which makes me think that its my alternator going out. This only happens when i have something that draws out electricity like a turn signal on or when i step on the brakes. I am thinking that it was a bad ground so i went and replaced my loose negative terminal fitting but unfortunately that did not fix it. This occurs at at random and the negative battery cable is secured tightly against the block. I have no idea where this loose ground is or if i have an alernator going out intermittently.

 

The radio has been acting up too now. This is so irritating. I wish there was a simple answer like a major relay or something.

 

Might suggest having the alternator and it's internal voltage regulator checked for correct operation, if the grounds are clean and tight.
