new_owner Posted July 6, 2004 Share Posted July 6, 2004 Gang, Something really weird I came across just yesterday on my 91 LS400. I was driving and Pushed the "auto" button to turn on the AC...my car made some rumbling scary noise and halted there. The engine died. I had turn off the AC, and re-start it again. This was repetable every time I started AC. Have no clue on what happened suddenly?? Anyone experienced this before? Thanks, Quote Link to comment Share on other sites More sharing options...
flanker271 Posted July 6, 2004 Share Posted July 6, 2004 When you drive with a/c on but without the auto feature on, does your car make a whining like noise? If so you have bad compressor. Otherwise, do you mean that you couldn't turn on your a/c at all? Everytime when you press the a/c button, an electric signal is sent to the a/c compressor clutch which engages with the drive pulley. If your compressor is bad, it will freeze up, haulting the accessory belt, thus stopping the engine. Quote Link to comment Share on other sites More sharing options...
VMF Posted July 6, 2004 Share Posted July 6, 2004 hmm really strange problem, what if you just turn on fans and then press on the ac button? put the temp to max first and check if its gonna die. Quote Link to comment Share on other sites More sharing options...
Zdeno Posted July 7, 2004 Share Posted July 7, 2004 I had the same problem on my 1991LS400 - The AC Compressor was locked up. Quote Link to comment Share on other sites More sharing options...
1UZ-FE Posted July 7, 2004 Share Posted July 7, 2004 I had the same problem on my 1991LS400 - The AC Compressor was locked up. i believe thats what new_owner's problem is. i've heard of and experienced this problem before on many different makes and models of vehicles. just like you, as soon as you press "auto" or "ac" (both will turn the compressor on), the engine simply dies. 10 times out of 10, it was a locked up AC compressor.

new_owner Posted July 7, 2004 Author Share Posted July 7, 2004 Thanks Guys.. So assuming that the compressor is locked up..is this is a easy fix? Would any service station do this for me..or I will have to go to the dealer? Quote Link to comment Share on other sites More sharing options...
Zdeno Posted July 8, 2004 Share Posted July 8, 2004 I bought the compressor here http://cgi.ebay.com/ebaymotors/ws/eBayISAP...sspagename=WDVW and I leave to fix it in my local A/C shop. It works fine and it comes with one year warranty. Don´t forget to change the drier ! I also let change the expansion valve. Good luck !
