dealership charge to replace vacume hoses ??

[skooterbum]

has anyone paid the dealership to replace there vacume hoses ?? i have a 99 blazer 4wd with the 3 button switch on the dash. my 4wd is not working. i got as much info from this forum as i could find to troubleshoot my problem. as i tore into things i found a vacume hose that hooks to the diaphram that is located under the battery. as i traced the hose i found it to have a huge hole in it near the distributor. from there it goes down the side of the fill tube for the tranns and then on top of the tranny. there is no way i am physically able to replace these lines on this thing so off to the dealer it will go. does anyone have an idea as to the cost i should expect for this repair ??
thanks
