1993 Chrysler Town and Country Bendix 10 sucks worse than a

So I have a 93 Town n Country with the Bendix 10 brake system. Recently the pump stopped running at all. I thought it was a little too complicated, so I took it to the dealer. They called me the next day, and said that the pump was bad, and would be replaced under warranty, and that I need a ABS relay at a cost of $195.00. I told them fine to go ahead and do it. The next day they call and tell me that they replaced those items, but I still have an electrical problem, and that it will cost another $170.00. I told them just give me my van back. I went and picked it up, and the brakes were exactly the same as when I dropped it off. I called the service manager and told him that I did not mind paying to replace the relay, because I knew it had some kind of electrical problem, but I felt they were just trying to change parts to see if that would fix it. He said it was working ok at the dealership, it just had an intermeittent problem. He said he would also give me another $100.00 worth of time to find whatever the problem was. I went home and checked things out, and as best as I can tell, the hot wire that comes up to the relay, that is red with a green tracer is dead. I am thinking that maybe the pump had shorted out and burned up the fuse link, but I do not know where any fuse link for it is. Also the relay they charged me $135.00 plus installation for looks like a regular old bosch relay. At this point I am upset. This is a good van, but I cannot afford to sink much money into it. The trans was rebuilt at 106K, and a cooler added, and I keep everything else on it working correctly. If someone answers this question, please have specific knowledge of the Bendix 10 system on a 1993 Town & Country. Thanks.
