Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. There is only one relay involved in the 2005 Xb air conditioning circuit, it' called a HTR Relay and is located behind the lower finish panel (the panel where the drivers knees would be if they are sitting in the drivers seat) in that fuse/relay box.
I don't think I have ever seen one go bad so I'm not sure what you're looking at this specific relay. Do you have anymore info as to whats going on with the A/C?
There isn't a clutch on this compressor. Just charge the low side with the R134 (I am assuming that you dont have an actual a/c machine and are using a can) and that should provide enough pressure in the system to allow it to engage. Does this make sense?
