Anybody do this on a 2000?

My recirculation button led is flashing and my recirculating thing keeps cutting in out every 5 mins. Noise and pressure changes. There's used climate control ones on eBay for $40

Can I 'upgrade' ?

 

No, the connectors are different. You would have to rewire several things in order for it to work. Just replace with what you have and call it good.

 

it a can of worms to deal with if you're gonna convert, better to stick what you have and replace it.

 

Ok well then I definitely won't buy that.

so I just need to buy the standard have control module to fix this recirculator thing right? Or is there a lot more to it?

 

Just buy the entire unit. Your problem is most likely the unit itself.
