That is not normal, dealerships anymore do not know how to work on the new vehicles they sell let alone an almost 14 year old one that is a deceased model. I'm surprised they even made an attempt, usually they will tag you for a diagnostic fee and say sorry there's nothing wrong. My experience with these old cruisers that had HVAC cooling or heating problems were either, blend door servos, the HVAC control unit, or wiring issues. Now this old you could find yourself battling parts issues and finding some place that will want to work on it with results. Maybe an independent shop but good ones are getting hard to find these days.
Unfortunately Dealers aren't very enthusiastic about working on older models. I'd suspect one of the air conditioning compressor cycling switches is not working correctly and not turning the compressor on fast enough. If you have automatic climate control it could be a bad in car sensor or one of the control modules. The system could also be low on refrigerant causing the compressor to not turn on and off correctly to maintain the temperature. Hope that helps! Jim
