Review on 🔥 Spectra Premium 93069 Heater: Enhancing Heat Performance and Efficiency by Domonic Roberts

Perfect for 2002 Jeep Grand Cherokee. This is the exact same make and model of heater core sold at O'Reillys for over $90. Yes, installation is a hassle with @ss, but it's worth it. I also replaced the fan motor when I had the HVAC box, the bearings seemed very stiff. If everything works when you reinstall it and the interior lights don't work, the sensors don't work, the parking lights just make a clicking noise, then you need to unplug the center console and check the two ground connections on the airbag. Computer (next to the brake). There are two of them, G200 and G201. This area is almost always quite uncomfortable as I had a lot of sticky black tar due to the previous owners fondness for soft drinks. This area gets pretty rough and you will need to unscrew the two ground wires, CLEAN the connections and make sure they are tight. I did that and everything works great again. Also check the ground jumper from the engine block to the firewall, this jumper is all that connects the battery negative terminal to the body and is barely enough to work. Clean the connections again and also check the ground on the dipstick screw. This will help ensure a reliable electrical system.
