GQ Patrol air con wasn't working right and now is frezzing findout how

hi, we have a GQ patrol and have always had trouble with the aircon not working the way we thought it should, we have had it regassed and a new belt fitted and only works a bit sometimes and never what we would think it should and the fan didn't seem to blow out much air. so recently hubby thought he would take out the fan to see if it needed the blades cleaned as it was also a bit noisy, so popped out the glovebox and took out the fan which did need a clean, he noticed the bird cage (or thermostat cage) and this was covered in fluff and bits of hair so he removed that to clean it, then looked in behind where the cage was and there an area that was chocker full of leaves, fluff and bits, the fins on the evaporative cooler were also clogged up (about 90% clogged) and looked corroded, so got all the leaves and bits out and used a bit of wire with a small hook on the end to pluck out the bits from the fins, we used the cleaner to suck up most of the bits and left it open with a heater blowing on the fins to dry it out, then used a hard toothbrush taped on a stick to clean off the rest of the fins then vacced it out again and put it back. the difference it made is totally amazing, our GQ is now an ice block it now works better than we ever thought it would, so we thought we would share this with others as it a relatively easy and no expense job with great results.
