Question about 1998 Chevrolet Blazer

1 Answer

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

I have a 1998 chevy blazer (s-10) 4.3L 4x4 it keeps blowing the #15 (10amp) 4wd fuse, if you put a 10 amp fuse in it will blow the minute you turn it on ,then we put a 15 amp in it seems to do it when you...


check transfer case electrical switch, sometime if it bad it will also blow the fuse. don't recommend you put any higher fuse than recommend, If the fuse blow there is a short some where and by putting higher amp fuse you might short or burn something else beside the fuse. if that check out than check your transfer case motor, might lock up and not allowing the motor to turn instead it short the fuse. don't drive the car, just leave it in park, put correct fuse amp back in and unplug transfer case electric switch and turn the key on (dont start the car) and see if the fuse blow; if not plug it back in and see if it blow the fuse. if that is not the case, unplug transfer case wire, and do the same and see if it blow the fuse.

No heat after replacing battery


Replacing the battery has no effect on the heating system. Do U have a temp gauge to know if the engine is getting up to temp? and then the heater should put out heat. If it doesn't then U should look at replacing the thermostat

No spark when trying to start the engine on 98 chevy blazer


Check for dead battery. Test wipers, radio, headlights and heater fan. If all work normally, battery is probably charged and you may have bad starter or alternator ....

Good luck...

Yes it screws in on right side of tramission and you will need a 7/8 inch deep socket to remove it. You may be able to clean the old one once it is removed. There is a little ball thatgets dirty and may you can get by with cleaning it. Good Luck. Ed

Windshield wipers


Mine did the same thing on my S10 pick up.
I took the motor off, drilled out all the rivets, cleaned it made sure the brushes and commutator were OK, greased the drive and put it all back and no improvement. I bought a replacement motor from here: rockauto and they have been fine ever since.
