91 4runner rear heater question
Well my 4runners rear heater is not blowing out hot air.The fan is working and the coolant is full so I was thinking it was the rear heater core.It does not leak or anything so I am kinda stumped.Could it just be clogged?

quick stupid question....Is the heat positioner all the way to HOT.....
if you crawl under your rig you can see the coolant tubes runnin back and then into the cab, they could be dented and blocked,

The lines are almost rediculously small that feed the rear heater, and they clogg rather easily in my opinion. I had to take them out and remove a major blockage. It's kinda like trying to unwire your house then put it back. Good luck with it though.

Just out of curiosity, since you live in a warm climate, why would you go to the trouble of fixing it? I'm a northerner and rarely have used mine since 1990...
Just my 2 cents...

It's not uncommon to drive down a backwoods highway in that area see and see 10-15 foot tall walls of snow on both sides of the road.Try turning the rear heater on and letting it run for 10-15 min while driving. When I first bought my runner, the rear heater wasn't blowing hot air either - so I let it run for a while the first time it works just fine now. I love the rear heater, it's a nice way to warm up the truck on long drives (or whenever) without having hot air blowing directly on you.
