The A/C compressor has seized and the compressor clutch appears to be disengaged, but sometimes I hear noise coming from the engine compartment and the engine does not run smoothly. If I stop, turn the engine off and re-start the engine, everything goes back to normal. This has occurred 3 times in about 100 miles. Any ideas on what is happening?
When I turn on the air conditioning, everything seems normal, the compressor appears to be working and the fan goes on, but only warm air comes out of the vents.
Where should I start to figure out what is wrong? I have Durametric , if that can help.
Hi all. Was driving my 2003 996 cab 2 days ago. I heard a strange noise from the rear and pulled over. I smelled a burning type odor and a small amount of white smoke was coming from the trunk vents. Since that time the a/c is not producing cold air. Fan still produces plenty of air, but it isn't cold. Am I looking at a blown compressor here, or are there other possibilities? It gets rather warm in South Carolina, and sometimes rather than dropping the top I use the a/c. Any input from any of you would be greatly appreciated.
Thank you in advance,
The car has been awesome 2006 987.1 30k miles. The other day i took it for a drive and stopped after about 150 miles for about 30miins when I came out, all my coolant was on the floor. I refilled the coolant and constantly checked the temperature, initially it edged up to 180F but then settled back down to 175F and stayed that way all the way home. I was driving gently and kept cheeking the coolant level. Since then I found that I needed to open the coolant needle valve and drive around for 3 or 4 days to bleed the cooling system. I'm on day 2 and the coolant level has gone down slightly. Whenever I stop I check the floor and there has been no coolant leak.
I am baffled, anyone seen this before?
My A/C has been getting warmer over the last week to the point of just warm air. The compressor is engaging as I can see, hear, and watch the tach drop slightly as it does. I figured it just needed a quick recharge, but the low side pressure is ridiculously high at 90psi. Before I go and pull the world apart does anyone have experience with this scenario? Does this point to a bad compressor or Refrigerant Control Valve? I'm not really finding anything in the search dialog.
I have a vacuum and used it on other cars, but have never seen this "overcharge" high pressure issue. I guess I'll try to lower the pressure first, but I have my doubts it will fix anything.
Thanks in advance for any input.
