Narrative:

We had an equipment cooling exhaust off light come on with the associated master caution. We accomplished the QRH procedure; which had us switch the exhaust fan to alternate. The off light extinguished. Curious as to why we had the off light come on; we started a circuit breaker inspection and found the ground serv DC1 breaker popped. About that time; a flight attendant called and informed us that the direct tv was not working.I decided to get dispatch and [maintenance] involved. I used the call me feature in ACARS for dispatch. After several minutes we received a message stating simply 'copy'. I then sent a message requesting a frequency. No reply. I then sent a message stating our problem and the need to talk with dispatch and [maintenance]. No reply. I tried the call me feature again and finally received a reply; 'contact ATC'. We did and they supplied us with an airinc freq.once we had voice contact with dispatch we ask him to bring [maintenance] on the line. It took a few minutes as we listened to various phone menus and prompts to get the correct person. We then listen while the dispatcher; someone from the 737 desk and someone from the airbus desk tried to sort out who should be talking; but nobody was listening; let along to us; the aircraft with the problem. It took a few minutes to get the 737 desk on; only to find out he was an engine guy and not airframe. Eventually we were transferred to the airframe desk. During this time; the flight attendants called to inform us that all the toilets were not flushing.once we had the proper person on and explained our situation; he asked if we had accomplished the appropriate QRH checklist and that the off light was out. After we confirmed the off light was out and checklist complete; I ask if the problems reported by the flight attendants and the equip cooling exhaust off light were associated with the popped circuit breaker. He said that he need to do some research. Maintenance came back saying the he thought they were related; but did not sound sure. I was not confident with his answer and asked what else was on that circuit breaker. He needed to do more research. While we were verifying that a toilet related cbs were not popped; I found that the oxygen man cont circuit breaker had popped. I informed [maintenance] of the new circuit breaker. His only suggestion was to not push them back in. He still had not given us any new information as to what was on those breakers and/or if they were related. We asked ATC for priority handling to [the destination]. Our conversation with [maintenance] lasted for about 35 minute with most of that time being research; yet not coming up with even the simplest information. Dispatch also had no input. 20 minutes from [our destination] we terminated the phone patch to concentrate on our arrival. We decided that we would [advise ATC] and continue. I was concerned about having two seemingly unrelated circuit breaker's popped and not getting timely and satisfactory information from mc. We did not have any flight or nav issues. There were no odd odors or electrical smell in the aircraft and no other circuit breaker's popped. After landing; we got another master caution and noted the pseu (proximity switch electronics unit) light on the overhead illuminated. Upon reaching the gate; line maintenance was waiting for us as directed by maintenance control; but with no information of our situation. They told us that maintenance control did not inform maintenance of our problems; just told them to meet the plane.to summarize; I did not get the support we need from [maintenance] or dispatch. It took too much time and effort to talk to dispatch and once talking to [maintenance]; they could not supply timely and relevant information; in fact; it was a waste of time.
