Hello!
I was hoping someone either had a similar problem or had an an answer to this problem I have with my 1995 4Runner. I've had it for 5 months and love it but the A/C goes out just after the engine gets to normal operating temperature. I bought the vehicle from someone in Denver, CO and moved it here in mid-winter. It had always been in the Denver area and the A/C system probably didn't get much use. The high and low side pressures are very normal when it is operating. I did some previous research and checked to make sure the water temp switch was grounded, replaced the expansion valve on the evaporator and replaced the receiver drier at the same time. I've tested the relays and the resistance was normal. It is like clock work though, 3-5 minutes after the engine reaches normal operating temp the A/C just stops working. I'm convinced it has to do with the water temp switch because it looks like it's tied in on the wiring diagram. Any suggestions would be greatly appreciated. Thank you. Todd - Oklahoma
