Climate Control Module Reset

I replaced the battery in my 1998 Chevy Blazer and now I don't have heat. I have taken out the RDO fuses (which was recommended to me), put them back in, started my Blazer and there was heat for about 20 seconds, then it turned cold. I don't understand why replacing the battery would effect the heating. What can I do?? What do I need to reset?? Thank you for any help you can give.

the problem is the blend door actuator. Its is located behind hte glove box. (as far up and to the left as you get get with your hand). The gear inside the motor will crack if it is overdriven. As far as the re calibration, pull the rdo fuse(s). wait about 30 sec. replace fuse(s) turn car to run wait for 40 sec or so. you should be able to get a flashlight and watch the motor turn back and forth. turn key off. you should have heat. if not, pull the motor out. very easy just two screws. open the motor can check large gear for cracks

Fuse box abbreviations

I need to know what some of the abbreviations in the fuse box stand for. I am trying to determine if its a fuse causing the tailights to go out periodically. It is very different than the fuse block in my '79 truck. I'm thinking its a computer brain problem because of other issues going on, but I want to check the easiest things first, so trying the fuses. Thanks, Yvonne
