The girlfriend has a 1996 Bonnie, non SC, and the belt snapped. We see the routing of the belt, but searching posts, all we see is for the SC. Does the splash guard need removed, etc. or what needs to be done to replace this dang belt. The tensioner has been replaced and hooking up the belt was not a problem.

I think you have to move the engine mount to get the belt on correctly....I'm not sure. There is a pic floating around somewhere with the correct routing. Someone will chime in shortly

There is a pic on the radiator support from the factory.

This is from what i remember of helping out on an L36 Belt...

You need to support the engine by a jack and piece of wood, and undo a mount or braket that it'* between.

the belt routing is in the owners manual as well, its under the section for engine specifications i believe.

there is a post a couple below yours that i made regarding the exact thing, same year and everything, have a look. http://bonnevilleclub.com/forum/viewtopic.php?t=37724

She says they changed the tensioner, on the side of the road, and it didnt take 30 mins, it was changed about 2 years ago. Also, I wondering if the belt going has/had anything to do with the AC not out of the vents, it only blows out the defrost and the floor, could the belt going bad have an effect on the AC!??! EX; not catching the pully, enuff to run the AC?

Im familiar with an '88 Thunderbird TC, so I dont know much about the girlfreinds car, YET!!!

But mine is still cooler LOL, she dont think so, but...

NO i dont think it has anything to do with the A/C. My 1994 Bonneville done the same thing and it was a vacum hose that had come loose. It came loose from a place on the firewall next to the brake master cylinder. It looks like a little ball, that it came loose from. I dont know if this helped but i tired

The belt and AC are completely unrelated. The belt is a pain to change, but with the link and owners manual you should be all set.

On the vents. There are many threads here recently regarding this . Search on vents and blowing. The basics are you are missing vacuum to operate the system and it is defaulting to floor and window.

James Tharp, Echo, Nick * and Popatim all have great knowledge and first hand experience lately. Search for their posts about A/C and vents and you will have everything you need to get this fixed.

The vent problem is most likely a leak in vacum system check broken hose.

Master... we need to give a little more information that it probably being a broken hose.

The broken hose Master is mentioning is typically you are missing vacuum, the tank is located under the front of the passenger side fender. There is plenty of easy stuff to test in front of you. Good news is you can fix this easily if you follow the suggestions and info in the link below. Read the whole thing before you go running out there though. There'* tons of good information.

The steps I would take are these
Test vacuum at tank
Test vacuum leaving tank
Test vacuum entering car
Test vacuum in car
Test vaccum where ever possible inside car to the actuator that moves the air door.
Then aim at the programmer....theres a nice fix to that, I believe in this link
