Hello, I have an issue with the heating system on my 2003 Accord EXL. the driver seat heated gets a hot spot under one leg. It gets very hot and then the seat bottom stops heating completely. The back still heats. I have had it to the dealer 2 times for the issue, they replaced a part the first time, a seat heater of some sort. The second time they said no trouble found. This time, they ordered a seat bottom which Im assuming has a heating unit contained within. Has anyone seen this problem?. Thanks.
