Airconditioner Cutting Off

[mackayboi]

Hi,
I hope this thread hasn't been started somewhere else... Admin please move it if need be.

This post relates to the GQ Nissan Patrol

For the past 3 months I was getting my air conditioner running nice and cold for about 5 minutes, and as soon as the engine heated up, the aircon would totally shut down, blowing hot air into an already hot day.

I found a solution but I am not sure the implications/problems this solution may bring.
I found a temperature regulator under the glove box with Two wires plus a copper? tube exiting a small silver box. I soldered a piece of wire between the two wires that attach to the regulator and this seems to prevent the air conditioner shutting down.

A fridgey told me that the only problem was the temperature gauge/valve for the aircon was broken and that is would cost me around 600 dollars to fix. due to the fact that to access the valve i need new regulation gas in the place of the original gas from pre-1994. I declined the quote, and found this solution.

Has anyone else done this modification?

Thanks.
