Engine Size: 6 liter
Refrigerant Type: R22
Country of Origin: Japan
Hello. I am new to this forum.
The air conditioner in my '89 Toyota pickup (4x4, Xtra cab, 6 liter V6) is not cooling. The fan operates normally at all speeds, but the air coming out is not cool at all. Based on RPMs increasing, it seems that the compressor is engaging normally when the A/C button on the dash is pushed in. Around the time it stopped cooling, and 1 or 2 times since then, the 10 amp A/C fuse has blown 2 or 3 times, but I have been able to engage and disengage the compressor a number of times without it blowing.
The first time that it failed to cool, my wife was driving it and she said a bad smell filled the cab, but she wasn't able to give me a better description of "bad".
I would appreciate any thoughts on what the problem might be and next diagnostic steps or remedies to try. Thanks in advance.
Need pressure readings to start with at low and higher RPM.
I hope you typo'ed the R22 as the refrigerant
Engine rpm may go up when you press the button, but that doesn't mean the compressor is actually engaged. Look at the clutch plate on the front of the compressor and confirm that it is spinning.
The bad smell may have been the belt burning up because the compressor is seized.
