if you look at your underhood sticker it should show how to route the belt w/ or w/o ac. you may be able to just get a shorter belt but, if that comp pulley is in the way you'd have to lose the comp.

p.s.: if you're not running the a/c taking the belt off the comp won't free up any extra h/p.

While yer at it, bypass that damn belt tensioner pulley.
It sucks just as much power as that free-wheelin' A/C clutch pulley.

bypassing AC =>RE: 4.7 ac
IP: Logged

Message:
The pulley probably isn't free wheelin when the clutch is engaged and the compressor is being driven.

Anyway can I have your AC compressor? The bearings just went in my 2000. I looked and tried to find a way to bypass the compressor pulley but I don't think there is a way without adding another pulley somewhere. It appears that a shorter belt wouldn't hit the compressor but it would rub against itself at one point near the tensioner.

I would like to get rid of my AC as it too expensive to fix and I don't really need it.

If anyone has a way I'd love to hear it.

I spoke to Dodge dealer today. They sell a bracket and tensioner and possibly a different belt that would likely give you the no air option. About $150.

Hey ... I just got a 4.7 to replace my 98 3.9L. Well long story short .. My compress locked up hard after a few hundred. The Truck would not start with the belt on so I got a shorter belt and routed the A/C compressor out. What you need to do is go right from the Alternator to the tensioner, I found a Diag with the short belt routing, but I wanted my Ps pump so I just looped that in. It has worked like a champ so far. Tomorrow I can get the belt Number if you still need it.

Finally got back to this forum.

I did give in and get my AC fixed.

The number for the belt would be good to have though for future use. It would be nice to be able to order a belt by length rather than model-engine size, etc...

thanks for the info

Alex

ac / heat fan =>RE: 4.7 ac
IP: Logged

Message:
Can't say for sure but my experience with an older Mazda truck was a unit with a few resistors (just a coil of resitor wire in this case) connected in each switch position. They were burned up. In high position there is no resistor - simply direct 12Volt to the fan/blower. A schematic would show if the component exists for the Dodge but finding it might not be as easy. In the Mazda It was located behing the glove box.

This isn't a Mazda though so who knows.

Quite possibly the switch internal contact mechanism is broken
