Snowtoy,the A/C was put together by the p/o with different year parts I'm sure.It's a 134A now..however the A/C amp board in the truck was not working.It had juice going to the A/C amp board from the A/C button but not coming out the other side.After trying three used boards,my mechanic just bypassed the board with a jumper wire on the board plug....A question for you or others,if I had a new A/C amp board which has an idle up and temp adjustment on it would the inset screw adjustment for temp lower the vent temp or would I be wasting the $89 the Toyota dealer wants for the part?
