Hi I have a 1991 honda civic hatchback std and for awhile the blower would only work when I had it on recirculating instead of vent. Then tonight on my way home from work it stopped working completely. My A/C and heat would work on recirc but never on vent. Is this a resistor issue? Should I start by replacing it, any help on how would be appreciated. Please advise.

 

If it was the resistor then it would work on vent. You just wouldn't have all the speed settings. I think your control panel is bad.

 

Well I tapped on the unit under the glove box and it came back on. All the speed settings work. Let me explain further when I put it on vent it seems like it is blowing very very weak, and is totally useless. On recirc it is strong enough to kinda defrost my windows after about 30 minutes. I don't know what to think but I am glad it's working now.

 

Which unit? The blower motor or the resistor? Is it blowing weak? Check the electrical connections.
