I should be checking my messages more often.
That location I suggested for the relay was for a GS300.
The relay location for the RX is at the driver side lower panel.
You'll see J/b 1 and just to the right of it. There is a white connector.
Below that is your HTR relay plugged in through the back side.
I joined this site to contact you. Your advice to a gentleman on his 1999 rx300 was spot on. I have two questions: I can not find the passenger kick panel junction box on my 1999 rx 300. I bought the 5 prong relay, and want to advoid purchasing the blower motor control module if possible. I removed the panels on both sides of the passenger floor board, but no junction box. Secondly: we are considering a 2007 LS Hybrid. Will we have and major problems with this year and model? We are going to pay $30,000 ish. Love the look and milage, just wondered how much life is left in it?
