extra heat?

Anyone use something like this for extra heat?

Welcome to Sports Imports LLc.

My heater works - but it doesn't blow hot air - only warm air. It takes the chill off, but as always I want more. I'm trying to decide between something small like this or a bus heater installed under the rear seat.

Your TJ's heater is MORE than capable of blowing out hot air. I'm betting your heater core is simply clogged and full heat can be restored by flushing it back & forth repeatedly with a garden hose.

Garden hose? I'll need to wait until it gets warm before I get out the garden hose. How about if I have the rad flushed by a shop?

Flushing the radiator won't help, you need to have the heater core flushed. As long as they're the type of shop that will do it right and keep at it until the water flows easily through the heater core, go for it.

A typical Quick lube flush with a machine will not get it, The procedure Jerry described using a Garden Hose is the best bet.

A leaky blend door could also cause low heater output.

midget - some dont realize that below a certain temp the wrangler, while in perfect working order, will not blow hot air. I had a heating issue too, back flushed the system, un clogged the heater core and man did she blow hot hot hot! until it was 25 degrees and below. Seems they dont do well in our temps, in theory yeah they should push out a ton a hot air, but they dont.

IDK I live in SE WI and it is ohhhh! about mid teen's right now and when "Silver" is warmed up I can take my jacket off and only wear a turtle neck and long jon shirt...OK may be a sweater if it's really blowing out there. I plow snow for a living and it gets down into the negative digits when I'm out and I need a jacket then.

You wear turtle necks? I agree the Jeep's heat can be plenty powerful. I drive 30 mins down the highway to work in the snow in Denver without the back side windows (somebody stole them). Take the $175 you'd spend on an additional heater and fix the one you have.

Something don't sound right...within 15 minutes, my Jeep is leaving me considering rolling down the windows (or taking the top off...lol) and lately it's been about 5*F in the morning.
