Comments about ToughOne or Ready-Aire Heater Core:

Ordered online and picked up at store. The box had been re-taped when I picked it up, and I made the mistake of not checking to see if it was ok. It was not a new part.

Comments about ToughOne or Ready-Aire Heater Core:

Bought this for our 1999 Jeep Grand Cherokee Limited V8. Followed directions on a two part youtube video. This was a HUGE job! The dash has to be totally removed, and ac has to be dicharged before new part can be installed.

Comments about ToughOne or Ready-Aire Heater Core:

The product did not fit 100% to OEM, but was acceptable. Honestly, I only replaced this part because I was in replacing the AC evaporator core. Figured I would replace the heater core while in there, as it is a lot of work getting the dash out of a 99 Jeep Grand Cherokee.

    I have a 2000 jeep Grand Cherokee Limited.I cant get the heat to come on. During the summer the ac work fine. Now that it is Fall I cant get it to blow heat. If I push button for circulation mode it fog up window. Will that be heater coil or something else? Last year I had heat but it will stop blowing heat then it will get cold if I turn off for while it will blow heat again.

      Hi Sytari, Unfortunately, without the presence of your vehicle we are unable to diagnosis the exact problem. We would suggest you to check your vehicle with a certified mechanic for a proper diagnosis before buying the parts that may/may not solve the problem.

      A:

      I recommend visiting your local Advance Auto Parts store and purchasing Haynes Repair Manual. The book will provide you with replacing the Heater Core for your specific vehicle. It will also direct you step by step with detailed instructions on the replacement process for any part on your vehicle.
