Im posting this to get some insite of what may be the problem with my mom old volvo. Its a 1991 volvo 240 and the a/c does not blow cold.When she bought the car used the a/c blowed very cold and worked perfect. After a couple of months the a/c started to blow hot air, so we took it to a shop and had them convert it to r134. After two weeks the air blowed hot again. The shop said they could not find any leaks and wanted to charge my mom again for a recharge. So last week i filled it up with r134 myself and it still blows hot air. My mom just bought a mini cooper and i will be useing the volvo as a daily.Any suggestions?

The outer pulley on the compressor will spin when turned by the belt, but look to see if the center of the pulley is also turning with the AC on - suggesting the clutch is engaged.
The best way to know whats going on is to measure the low side pressure. A lot of the 134a cans from the parts store have a gauge on them .... |

Thanks for the reply.The center the of the pully/compressor is not spinning with the a/c on. So i assume the compressor needs to be replaced?If so any suggestion of vendors with a good price on them. thanks alot. |

QUOTE (yoda @ Jun 17 2009, 04:25 PM) So i assume the compressor needs to be replaced? Not exactly (IMG:style_emoticons/default/smile.gif) The problem is either a leak somewhere and the low pressure switch has tripped, or an electrical problem with a switch, relay, fuse, or wire. My guess is a leak somewhere since it lasted two weaks, but you need a pressure guage to know. How much R134 did you add back in? |
