I'm getting a EB 1 416 Error code on my climate control..found out it means coolant recirculation pump..Im not familiar with this part..what is it and where located. Found out my 134A is low, could this be causing the error code to come up..? Thanks for any help.

 

Coolant pump is on inner fender on passenger side. Depends on the engine it is often under air filter.
Those are needed if you drive in cold climates and stop a lot. It also is needed for REC option.

 

Thanks for your response..what is a REC ?

 

It is REST, sorry
You should have the button on climatronic.
It allows you to warm up the cabin after engine shut down for about 1/2 hr using residual heat.
