or your ac is marginally effective.
- to little, or too much freon
- compressor weak
- obstruction in the freon flow
- engine idling too slow
- obstruction in the air flow thru the 'radiator' (will keep it simple here), or radiator/ac fans not working.

Somewhere I read that the intake vents (near the windshield wipers) need to be kept clear of snow and ice. I would think that if you were satisfied with using the "recirculating air" mode it wouldn't matter. Is there something I'm not taking into account ?

Generally, the recirculating mode is not recommended to be used for long periods of time, as this allows the cabin air to become stuffy. So you want to use external air most of the time, which means your intakes should be kept clear of debris.

You must not have a pet, or an uncle Louie that let's one loose every couple mins.

Its simple to check it. You should have 2 water lines going inside to the heater core. Feel each line. Are they both warm, hot? Its simple to check from there. air
#813 of 839 Hose left loose...is the system ruined?
Jun 05, 2011 (10:05 am)
If a hose has been bad and/or left loose for an extended period, does the contamination ruin all the components in the system?
I recently purchased an '85 exotic car that had been in storage for a few years. Seller did extensive work and maintenance on the car to put it back in service but said the AC didn't work because the orig hoses were bad. He had removed the compressor belt. It turns out that a hose fitting on the compressor was also left completely disconnected; probably when the timing belts were replaced a year ago. I figured on new hoses and a rebuilt compressor, but should I expect to replace everything...evaporator, expansion valve, etc.?

No. If you plan on replacing the hoses anyway I can't see how the other parts would have become contaminated. The receiver/dryer will need to be changed out also since it's probably absorbed a lot of ambient moisture. If in doubt the entire system can be flushed out prior to evacuation/recharge.
#815 of 839 Problems with my AC / Heat
Jun 08, 2011 (1:08 pm)
I have a 2003 Mitsubishi Galant and i am having AC and Heating Issues for example: When I turn on the AC it will work for a little bit then stop working, sometimes if I let it don't run it for a while the AC will come back on. On rare occasions the AC never kicks on at all....When I run my heat...the heat never gets Hot like it use to when the car was newer...It is warm / lukewarm....I am not sure if these issues would be related in any way...Any help will be appreciated, thank you.
