Glad to hear the heat is better! Which style dash do you have and was Trevor able to wire it up to work with the existing HVAC controls (fan switch, air mixer, etc)?Trevor at https://www.british4x4specialists.com/ installed mine. I'm pretty happy with it thus far, but it hasn't been warm enough yet to do a thorough test on the AirCon side. The heater is vastly improved over the OEM one however. The limiting factor for heat is what can the engine produce.
