i have ford escape v6, it has check engine light but driving seems to be normal, on the other hand when battery light fluctuate it looses power for split seconds then back to its normal driving condition?

just my additional details: I have also experienced couple of dead engine when turning-on a/c while when a/c is not ON battery charging excellent (13.4-14.1 volt reading), since then I went to a/c shop diagnosed the car until it has a verdict of changing the evaporator because leaks is all around and it has clogging in the tubes..

after changing the evaporator it work fine, however, the engine light came-in, i did the reset by disconnecting battery for 15minutes, drove the car no engine light for a day then engine light back-on again, looks like it can't be fixed by only resetting the ecu.. anyone out there experienced the same, how did you fix it?

hi Tom, i'll try to get codes but in my location looks not to have a friendly shop to get it available, surely I'll try to look on the a/c belts - replacing suggestion, although i asked the a/c mechanic to also check the belts and told me still good and looks new this is only 5days ago..

Thanks Tom.. aside from getting the codes scanned, any more suggestions for DIY check/troubleshoot that may caused this problem?

hi there, looks like my engine light went off for almost two weeks now - thanks may be on battery reset, i had check also vaccum hoses making every sensors fits and its ok - well, except for the battery lightin-up contributory to loss power when driving, do you still suggest to get codes with no lights within it? any help out there will be appreciated..
