Narrative:

First aircraft was assigned to our flight ZZZ-ZZZ1; was nose number XXX. It had 2 deferrals: #5 slat overhead and le flaps lights inoperative and right wing ice illumination light inoperative. MEL card required a visual check of proper position of slats before takeoff and landing. Since flight was at night; I called maintenance and asked how I could do a visual check with light inoperative? He said I couldn't and that one of the deferrals had to be fixed. I called dispatch and refused plane; around XA10. Departure scheduled for XB04. Scheduled arrival was XC31L; 29 mins of margin for curfew. New aircraft assigned. It had a deferral for #2 slat lights inoperative due to in transit lights coming on in flight. There were 4 reoccurring write-ups in past 3 days for same issue. First fix was cycled flaps on ground could not duplicate. Second fix was change out position indication module; ground check normal. The incident was from crew saying they cycled flaps and light went out. The 4TH incident was an open log write-up inbound so it was being deferred for our flight. Dispatch called me in operations to let me know about new aircraft that had same issue but it had been fixed. I asked him what the fix was and he set up a 3-WAY call with maintenance supervisor. As soon as maintenance came on the line; dispatch said we have captain on the line and we would like to know what the fix was. Maintenance answered rudely; 'maybe if the captain would read the signoff he would know.' I politely responded by saying that this was the second plane with similar issue; and this incident was the 4TH one in 3 days. He said it was the first. I had plane history with me and walked him through the 3 previous write-ups on day 1; day 2; and day 3. Said he didn't appreciate me questioning his professionalism as a mechanic. I said I wasn't; but I wanted to know what the fix was. He said they replaced light bulbs in overhead slat panel. I said I do not understand how changing out a light that works would fix the problem. Maintenance went in to another lecture on how he was being safe and I was accusing him of being unsafe. I told dispatch that maybe it would be best to end this call. Maintenance hung up and I asked dispatch to get maintenance control on the line. He agreed and got maintenance control on. Maintenance control said that the write-up was 'illigit' and he wondered also how changing out a working light would solve the problem. I asked him to call ZZZ maintenance. I refused the aircraft because I didn't think we had a legal maintenance signoff. Dispatch agreed and supported my decision. I called the flight duty manager to fill him in on issue. I called zone to let them know that my first officer and I were in flight operations waiting for a new plane and that we were probably not going to make it into ZZZ1 due to curfew. They said local maintenance was trying to get hold of me and asked me to call. I tried but no one answered. I decided to call maintenance control back and asked him what he found out. While talking to him around XB45; maintenance supervisor and oncoming supervisor came up to flight operations. I asked maintenance control to hold on; I put my hand out and introduced myself to maintenance; who refused to shake my hand and my first officer's. He demanded rudely; to know why we were not at the plane and demanded I call to talk to another mechanic who changed the bulbs. Maintenance control ask to speak with maintenance and I gave him the phone. I called and spoke to someone who explained how changing out the bulbs 'fixed' the problem; because it ground checks normal now. I told him I was concerned that it didn't fix the problem because the problem was only happening in the air and that you can't duplicate the in-flight conditions on the ground. I hung up and found maintenance talking to my first officer who later relayed to me that maintenance said there was another air carrier pilot at the gate who said he would take the plane. Maintenance left flight operations. The flight duty manager had called me back and asked what the status was and I relayed to him that I would refuse this plane. He said zone had called him and asked him what to do with passenger who were loaded on plane. I asked him to have them taken off. Maintenance supervisor night shift; said that he couldn't figure out what the day shift guys did and wouldn't answer for them; but hecould remove the wrong fix and defer the #2 slat lights. I said that I wasn't comfortable with the status of the plane and what was legal or not. He said he would remove the wrong write-up from log history and defer it so I could refuse it. I called the new dispatcher and let her know what was happening. New plane was brought in from hangar which was there to replace first officer windshield for scratches; but usable. While preflting cockpit; a jumpseater introduces himself and I asked him if he told a mechanic that he would be willing to fly the plane. He denied making that statement but did talk to the mechanic. The jumpseater did say that maintenance said that if the jumpseater wanted a job at the air carrier that there is a new captain opening. Next day; I pulled up aircraft routing for the air carrier; and it had flown day 4 and experienced the same slat #2 indications again while on the ground.
