Re: A/C controls

I would think that there are modern controls that could work. Some modern systems work by pressures, some might work using electronics. I believe most systems once "on" have the driver "add heat" to make the temperature comfortable. Systems like in my '88 Mazda truck and '98 and ...

Re: Pulley Replacement 2012 Ram 1500 - Can't find any reasonable $$ parts

I was able to pull off the AC clutch off my Sanden compressor (1988 Mazda truck) without disconnecting/removing the compressor itself. Even practicing on a used compressor and borrowing AC puller tools from Autozone, I had to "engineer" some of my own pullers. Apparently I cannot attach a ...

Re: Cooling issues over time

bazzy - you stated that the compressor drive plate stops turning after a while. I suggest to concentrate on THAT.

Re: Cooling issues over time

I have noticed when this does happen the compressor does appear to have stopped so perhaps i could try that with the indicator light even if it is just a temporary addition to see what is going on. Yes, would be of GREAT value to know if the AC clutch is getting voltage when the drive plate (center...

Re: Cooling issues over time

I doubt refrigerant level would cause cycling between hot and cold unless the level was so low that it stopped the compressor engagement due to low pressures. Make sure the fan clutch or electric fans in the engine compartment are all working properly, especially if cooling is better on the highway ...

Re: Cooling issues over time

Similar symptoms to my 1998 Frontier AC about 1.5 years ago. I had soldered on a wire to the compressor wire on mine, which I routed to a blue indicator light on the dashboard. So I noticed that when my cooling stopped that the compressor was still getting positive voltage. So when the air went warm...
