I read on another thread that the brutus pro hd air conditioning runs for a couple of minutes then goes hot. I have that same problem. I notice it starts to cool then a red light swithches on down by the evaporator.
Can someone tell me what the issue might be? Thanks

See "2013 BRUTUS Service Manual Chapter 6 - HVAC". (I do not have this document)

Low on refrigerant?

If it's a new machine, there have been reports of Polaris dealers not knowing how much coolant to use when initially charging the AC system.

I apparently seem to have this problem as well. It happened not after 10-15 minutes though but after an hour of driving. It happened a few times, and for some reason, I'm feeling that the Air Conditioning Unit isn't as cold as it used to be. Could it be the clutch or is it something else? It feels like it isn't as cold as it used to be all things being equal. Any suggestions? How much should I look at getting this fixed?

Anybody have the service manual chapter that covers this?

The one chapter of the service manual I haven't been able to find anywhere is "2013 BRUTUS Chapter 6 -" >>HVAC

I apparently seem to have this problem as well. It happened not after 10-15 minutes though but after an hour of driving.
Quite a bit of heat makes it into the cabin (take a look under/behind the seats) so once the engine is up to temperature and running for an hour, the extra heat input may be overwhelming the AC?

One way to tell is to get a "vent thermometer", see how the AC is doing at putting out cold air?

The temp at the vents should be between 36 and 53 degrees after running 15 minutes at full throttle, depending on humidity. If temp is high, check that the heater valve is not bypassing. Could be a bad valve or actuator. Pinch off heater hose and see if it makes a difference. A solid lit LED on the module by the evaporator indicates a normal condition, compressor clutch enabled. LED off is normal, compressor disabled. A flashing LED indicates an error. Don't forget the simple things. Make sure the belts are tight. Make sure the condenser isn't blocked with dirt.

I drive mine on dusty trails a lot, and have to hose out the condenser a couple of times a summer and don't forget the filter under the dash in the cab, I have to clean it a couple of times a year also as it clogs up and just about halves airflow in the cab.

I have the Bobcat 3650 and my A/C wasn't working this spring, I verified the cabin filter and condenser were clear and checked my belt, the belt is a little loose, I still need to tighten it.

To fix my A/C I used one of the A/C Recharge cans that comes with the pressure gage to refill it from Walmart.
I have been using it on my cars the last couple of years so I already had it. I did need to by another can of recharge stuff.

I unscrewed the BLUE plastic cap under the dash and hooked up the recharge hose, 5 minuets later I have cold air again. The gauge on the can is set for the outside temp and you fill it until you are in the green zone on the gauge, I fill mine to the lowest pressure as I'm not sure how much it takes and if you over fill it, it won't work.

THIS CAN BE DANGEROUS, FOLLOW THE INSTRUCTIONS AND WATCH SEVERAL YOUTUBE VIDEOS ON HOW TO DO THIS. MAKE SURE YOU HAVE EYE PROTECTION AND LONG SLEVES AND GLOVES AS ANY SPILLED COOLENT CAN GIVE YOU MINOR FROSTBITE, WEAR GOGGLES AS A FROST BIT EYE MIGHT NOT MAKE YOU DAY

I have been doing this safely for 3 years now and it's not hard. remember to read instructions and watch the videos.
