95Blue4Runner

it just froze over outside and i could careless except for the fact that i cant defrost my windshield

I have a 95 4runner

the heater is blowing cold air

and i drove it for about 45 min the other night on the highway and off and it still isnt blowing hot. Any suggestions on what i can do to fix this problem. Or should i just take it to the shop?

got to move the little lever from the blue side over to the red side....

whats your antifreeze good for?

otherwise its I think there is a common problem with the linkage on the blue/red lever failing.

that was a joke right?

95Blue4Runner

is that something i could take apart and look at?

Stick your head under the dash and look for disconnected linkage. I had this problem. Take a look at post #10 here . to see how I rigged it.

is your engine getting up to normal temp or running cold? Could be the thermostat stuck open.

95Blue4Runner

how can you tell

im not completely stupid when dealing with cars, but ive never dealt with the thermostat before

is this something i could fix myself if it is stuck open?

95Blue4Runner

oh , and yes, i looked at the temp gauge and its running cold

if the temp guage is showing it running cold, then the stat is probably stuck open. get a new one and install it, take a minute or two and check out www.4crawler.com . there are some good articles in there on heating issues.

Thermostat stuck open. The engine will eventually warm up even if the t-stat is stuck open.

i shouldve taken care of this when it was 70 degrees outside

It won't be the fan clutch, mine is seized and I get great heat, way below freezing plus driving 70 mph. Won't be the t-stat either, after 45 min's of driving it'll be warm. If it isn't the heater control linkage, its probably a plugged heater core.

I guess you don't live this far north.

How did you get to that? Did you have to take the whole dash apart or just the blovebox?

my heater was blowing cold air and i found out it was caused by anti freeze being low.
check your anti freeze level.
i topped mine off and bingo.

i just flushed my heater core it was plugged just take the line off the fitting in the ngine bay on the fire wall ans put a hose up to it and blast away a huge chunk of this black crap coame flin out and now my heat works great

ChickenLover

No, I didn't take anything apart. It's right behind the ashtray, just stick your head down there and look up.

...true, but it wont get too warm. im actually running around without a thermostat and it only gets to about 1/8 to 1/4 of the way up the temp gauge, which may look somewhat "normal". the thermostat on the 3.0 is on the bottom end of the engine, the lower radiator hose is connected tot he housing. 3 10mm nuts and pull it out and take a look.
