theoldpaths Posted April 1, 2008 Share Posted April 1, 2008 I have a 90 LS400. When I turn on AC, the car bogs down and dies. Do I need to replace the whole AC compressor or could it be a "simple" problem? Thank you Quote Link to comment Share on other sites More sharing options...
TA in KC Posted April 2, 2008 Share Posted April 2, 2008 I have a friend who used to have an old Nissan Maxima that did the same thing. He had to replace the whole compressor. That might not necessarily be the case for you though. Is the clutch engaging when you turn on the A/C? Is it staying engaged or disengaging quickly?

I'm sorry, I know carpentry and computers but not a whole lot about cars. Quote Link to comment Share on other sites More sharing options...
RFeldes Posted April 2, 2008 Share Posted April 2, 2008 What happens at 35mph when you switch on the ac? Any loss of power? Quote Link to comment Share on other sites More sharing options...

I'm sorry, I know carpentry and computers but not a whole lot about cars. The clutch is the black thing that is on the front of the compressor. Look under the hood while the engine is running, then have someone turn on the A/C. The thing that starts turning is the clutch. Quote Link to comment Share on other sites More sharing options...

Ok, today while driving about 35mph I turned the AC on and it did not seem to bog the engine down at all, but I do hear something that sounds like bad bearings. While parked and idling, I turned AC on, this time it did not bog engine down. The clutch is turning when AC is on, but also makes a sound (loose marbles) like bad bearings when turned on. Where would you say the bearings are? Does that mean I have to replace whole compressor, or can that be repaired? Quote Link to comment Share on other sites More sharing options...
RFeldes Posted April 3, 2008 Share Posted April 3, 2008 I would replace the compressor before shavings get in your system. I would also replace the drier in case there is debris. and then pull a vacuum before replacing the freon. http://cgi.ebay.com/ebaymotors/A-C-Compres...tem160224608275 Quote Link to comment Share on other sites More sharing options...

I am not real proficient in auto repair. Would this be basically unbolt old one and bolt on the new one? It looks real tight down there.

theoldpaths Posted May 27, 2008 Author Share Posted May 27, 2008 Are there any tutorials out there on changing to AC compressor? What kind of freon does a 90' take? Thanks Quote Link to comment Share on other sites More sharing options...
