How To Fix "No Heat" In Your Jeep

[@kolejohnson73]

Use CLR in the heater core to dissolve the crap in it. Started at Chrysler in the 90s, the design and materials they used across the board in the heater core would collect all the scale and plug. Blow out the core with some air, use hoses to fill core with CLR and let sit about 30 minutes, then flush both directions with clean water.

Good tip! Thanks

[@paulsscooter]

great video, thank you for taking the time to make it and explaing it so well. I have 1999 TJ and will be doing this soon.

[@WheelinWithWally]

Awesome good luck!

The Blend Door Actuator in my WK is on the drivers side. So weird. I’m looking forward to see the next video.

My 1989 Wrangler is blowing hot air out of the vents while the heat and air are turned off. Any tips?

[@chadleake5703]

Great info. Probably why is wrong with mine.

[@WheelinWithWally]

I hope it helps you get it fixed

Did you need to drain the coolant first before detaching the heater core hoses at the firewall?

[@WheelinWithWally]

I did not. I expected some to leak out when I removed the hoses but it didn't really leak at all.

Have you watched NickinTime's video on installing a coolant filter? You wouldn't believe the amount of gunk his filter system catches!

[@WheelinWithWally]

No I haven't seen that but it makes sense

[@Fauncebrothers]

Why diddnt you show how much crap came out????

[@WheelinWithWally]

@@Fauncebrothers it wasn't much to look at
