Blinker problems

Ok i have a few questions. I have a 97 4dr 4wd Blazer. First off i was wondering if anybody has used seafoam and if there was an easy way of getting it into the intake. I know old carb motors you could pour it in there. But not sure about fuel injection. Or if seafoam is even any good, i heard it was but wasn't sure.
 
Also my blinkers just quit working. My headlights, and break lights work but when i turn my blinkers on nothing happens. They don't flash on the dash or outside.

Lastly i was wondering if anybody had any problems with their blazer not warming up very good. It's kind of cold right now where i'm at and i can drive my blazer all day long and the temp guage hardly moves at all. When it's warmer outside it will always warm up to about the first notch (not sure how hot that is) But when it's cold it doesn't hardly move at all. So is there maybe something wrong or is that normal. Is there anyway i could get it to warm up better?

About seafoam, I have used it on every vehicle I have owned for a long time.  I believe that if you unplug your MAF sensor and remove the intake duct work, you can just pour it down the throttle body.  On my Bravada, I used the PCV vac line to suck it into the intake, but I didn't unplug the MAF sensor so the truck kept on dying on me.

On the blinkers, you probably need a new relay.  Do your 4-ways work?

About the not warming up, it is quite possible that your t-stat has stuck open and is not allowing the motor to fully warm up.  How is your gas mileage?  Does the heater put out decent heat?  Is the upper radiator hose hot?

Yeah my 4way hazards blink just fine, but the actual blinkers wont come on when i try them. Could it be that the blinker switch is bad? I mean everything else on there works the wipers and cruise and all that just not the blinkers?
 
With the warming up the upper radiator hose feels hot. But my gas mileage isn't very good, it snowed a while back and i was using 4wd but i think i averaged around 11-12mpg.  Right now driving just normal i get like 15-16 and thats even on the highway. I didn't think this was very good but i wasn't sure how good they were suppose to get. The heater is somewhat warm, its not as warm as it could be i don't think.

your out of blinker fluid....durrrr......lol jk but really....you need a new flasher relay located directly behind the cigarette lighers. I'm kinda wondering if I need a new T-stat...I replaced it not too long ago when I got it a year ago...but since then have had the intake gasket replaced. Would this effect my t-stat? I've been gettin about 12 mpg and according to the temp gauge, it never goes over the 1/4 mark.....160ish??? i dont know....Its never even been remotely close to 210....never ever...help me out

If the temperature never goes over somewhere in the 170*F range, it won't move out of the fuel enrichment mode.  That is why I asked about the mileage.  But at 15-16mpg, that doesn't sound horrible.  12mpg does...

what is the quarter mark temperature on a 96 blazer actually reading???

Yeah my blazer has never gotten close to the 210 mark except one time when it was almost 90 outside and it was idleling for over an hour. So could that be the thermostat sticking open? And about the blinkers, so that sounds like the blinker relay under the dash?

yea...there will be 2 different ones that are pretty similar...i think its the smaller one...on the right... center dash

Ok i found them. Do they just pull out or is there a trick to it. I was afraid to pull too hard i didn't want to break anything.

yea..pull straight out...

You have a stuck open t-stat, I had the exact same problem last spring. When I replaced the t-stat the heater got a lot hotter. Then just recently it started again not heating up, so I flushed the heater core for the second time and flushed out the Dexcool since my engine had over 100K it was time for new stuff and I switched to the older style "green" coolant to see if it would last longer without clogging the heater core, time will tell. Dexcool is great in a newer car that has not developed a cooling system problem, but when I read about all these issues with the product and the problems that are linked to it I just want a measure of safety so I just replaced it so that it would not cause me trouble in the short amount of time left with the vehicles mileage before a rebuild....

DexCool has higher acid levels, this is what causes the clogging over time. It starts to turn into a SOLID. And when this happens the acid levels become like battery acid to your engine and cooling system. But GM will not recall it and many other MFG's are starting to use it due to it shortens the life of your engine and cooling system. I about cried when I saw the New 2007 Dodge Charger w/ a sweet 440 Hemi interceptor with that rotten DEXCOOL in it. Sad when they remake a classic and just trash it with junk like Dexcool. Even the Dealership owner said that his personal one he changed it out due to he did not want to trash the motor w/ that junk. That has to tell you something about Dexcool if a MFG's recomended fluid gets replaced by a 40+ yr mechanic and owner of a dealership.

Simply FUD.  Not true, any of it.  This is not a dexcool thread.  We already have one of them where all of the facts are laid out.

Hey guys thanks for the help. I got the relay replaced and i got blinkers...lol. I'll have to check into that t-stat when i got more time. But thanks for the help.

did you have to remove the dash board to get to the blinker relays?

And your positive your radiaotr is full of the proper mixture anti-freeze and water?
