Volvo: v70 T5 Climate Control fryed, mass air flow sensor, mass air flow

Question
I have 2001 v70 T5 - took car in for 65K service. Dealer found issue with turbo gasket and mass air flow sensor unit. Serivce call was $1100. When I picked up my car,the climate control was 'dead' - (ie., as if the car wasturned off). Dealer said 'That's Odd' - took it back in the shop, came out 30 min later and said that the ECC is shot and that it will be 1000 to fix. This seems crazy to me - I have read that when you disconnect the battery to service the car that sometimes electrical components don't work correctly (need to boot up under the right sequence) -- Anybody have any ideas? There is no way the car climate control just happened to fry at the same time it was being serviced on. Dealer is trying to tell me that it is just an odd coincidence? Since they replacedthe MAF,could it be a software problem? Any help greatly appreciated. Thanks

Hello Brian! It seems like that would be an "odd" thing to happen. But, I think that it is a separate issue. I do know that the climate modules on that year and model do have problems and it may need to be replaced. I would ask them if there is a software update available for the climate module before you replace it.
