Thinking of removing all those hoses leading to rear. Just sayin'. Wonder if anyone has done same or whatever. | | | Re: Serious Vibration when a/c on | Joined: Jun 2010 Posts: 18,286 Likes: 557 | Joined: Jun 2010 Posts: 18,286 Likes: 557 | Welcome to the site....I would check to see if the compressor is loose or the pulley is coming loose....

I disconnected the rear heat/ac in my 94 Dodge. All I did was tie the rear lines back out of the way. However I did have to replace the heater hoses up front to eliminate the splices and remove the conversion company's splices for the a/c lines. All I run now is front a/c and heat.

If it stays constant then you'll need to dig the dead leaves outta your blower wheel. | | |
