My 2004 Nissan Frontier has a built in thermostat - a thermistor that is causing the compressor to cycle off too frequently. I can bypass this without too much trouble by simple installing my own switch & relay to engergize the compressor clutch. My question is, in bypassing and making the compressor run non-stop (until I switch it off), do I risk damaging something in the system? With the current operation, everytime the outlet temp gets to about 55F, the compressor clicks off, resulting in pretty sad cooling performance. I remember some of my dads cars blowing way colder, even getting frosty around the chrome trim on the outlets. Any help appreciated.

If the compressor is cycling to quick this is not the thermistor in the evaperator, it is the low side cut out switch, assuming the refrigerant is full.These are cheap and easy to replace.Would you like a diagram? Tim

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!

I recently purchased a new 2017 Nissan Frontier. The blower
I recently purchased a new 2017 Nissan Frontier. The blower fan makes an annoying whistling noise when it is on 2 of the different fan speeds. It does this whether the truck is warm or cold and on all of the different heater modes. The noise has been consistent on those 2 speeds except for one occasion when it did it on 2 of the higher speeds. The service dept. at my local Nissan dealer where I bought the truck said that they tried the fan on another new 2017 Frontier on the lot and it made the same noise. They just said that's how they sound. The 2014 Frontier did not make this noise at all. They seem to be very reluctant to try to fix the problem. Any possible causes? Thanks. … read more
