Just had the air-conditioning checked today - it's extremely hot here in Adelaide (South Australia) with temperatures around the 37 to 39 degrees Celsius (98 to 102 degrees Fahrenheit). Gas level is fine, compressor is cutting in as required, no blown fuses etc. etc.

Anyway, it seems to blow cold air for a short time then as soon as I am out on the road it's blowing hot air. Needless to say very annoying.

Any suggestions are most welcome.

 

if its blowing cold air and then turns hot, it sounds like the pressure goes to high due to not enough cooling. as long as the fan works properly, I would check the condenser for the fins being clogged and clean it out real good.

 

Can this be done without removal from the Jeep? Thanks for the response.

 

I know must of your climate controls are vacuum controlled. Not sure if the temp is, but might want to check your vacuum lines.

 

yea, should be able to spray some cleaner on it and then use a pressure washer to clean it....make sure there isnt debris clogging up the air flow. after you get moving down the road, does it blow cooler air?

 

Thanks, I will most certainly check them out and advise back.

 

Well this problem of blowing cold air and then hot air seems to be dangerous for the condensor.
