A/C relay constantly kicking out
I have an 06 Tacoma V6 and had to have the A/C pump replaced and the
dryer. I have put in new relay's that were purchased at local parts stores
but they do not last more than a day. I was told to go to Napa and get a
higher priced one, well, they have the same as local - all cost about $16
and didn't last. I have ordered one from Toyota for $80 and am worried it
may be taken out as well. Is there anything else that could be causing
First thing that comes to mind when relays keep blowing out is a bad ground. The AC relay trigger voltage is fairly low (I think +/- 5V?) if a ground is bad and hovering at or above +/-5V, the relay can't react to trigger or even experiences a polarity reversal. My recommendation is to go through all your ground connections, clean them or reseat them. Replace all brittle ground wires and straps.
