I’m having the common problem with my 2007 TL where the heater control valve leaks this is the third one I’ve put in is there a better part out there or should I delete the valve I live in florida so I won’t need the heat really plus I have the heated seats or is there something else I can do?

 

Is it new and oem? Maybe the hose or clamp is the problem?

 

Agree with Peter....are you replacing with OEM parts or using parts store generic? I had my TL for over 12 years and that was never a problem I dealt with....nor is it a common one folks really complain about on here...at least not multiple failures in a short period of time like you have experienced.
