Hello, since 07/07 have an Avensis Kombi D4D and the seat heating driver and passenger was defective from the beginning. The heating mats were then replaced on guarantee. However, it is now that the seat heating with full setting (rotary wheel) never brings the desired heating power. My wife is very sensitive there. Again with Toyota I realized that with 3 other cars of the same type a seat test together with the master brought the same result. atein now also at the end. It seems in his opinion to be a Toyoty Avensis problem. Who can help me? Is the problem known? Does it bother you too? What can be done? Thank you Greetings Finanzleibi
