Just thought I'd share this with you all since a lot of us are putting these in our boxes. I bought them about 4 months ago and now changed this driver side back one for the 3rd time... I gave the guy 2 chances thinking maybe I got duds, after the 3rd I thought maybe I was installing them incorrectly. When looking to find the problem, this is what I found... Cheap $40 heater kit from Ebay, and yes, $40 for both front seats with everything included.... Just as Spencer from bean garage recommended, over factory fabric, under the clazzio seat covers.
