Hi,
I have an 2003 LC5 and its been trouble free bar the air con. Just after the warranty eneded(typical) I lost coolant from a pipe that was cracked of which I had to pay Toyota to fix as no one else would touch it. Its been fine since but recently I've noticed a drop in performance of the air con and after looking around I found that a plug at the base of the evaporator is leaking coolant - looks like some of the previously injected dye is dripping out. Back to Toyota and they confirmed and would have to replace the full evaporator unit and with labour, comes to about £600.
The plug at the base has a hex key slot (about 1") so it looks like it could be removed but Toyota say not. Has anyone any thoughts as to what I could do here please?
