My HV heater has failed. I don’t have any codes but it runs the engine instead of EV when the car needs to heat to. I’ve noticed more now as it’s starting to get colder.

I was thinking I’d swap it myself as it’s in an easy to access spot at the front left engine bay.

Does anyone have access to topix for the replacement procedure? I have an account but don’t have the workshop manual. It should be straightforward but I really want to check whether anything special needs to happen with the battery first.

I’m really surprised there aren’t more articles on this, given how often the (£900!) part fails.

This is where it is:

Unfortunately, I can’t offer any advice, but I’m very interested in the procedure. Mine is still working (probably just a matter of time), but we already replaced the one the wife’s I-Pace twice, and her car is a year newer! If it helps, it’s much easier to replace than the one in the I-Pace, which is hidden deep inside…

For things like this, when I think Topix can help, I just pay for access for 1 hour or 1 day, find the info I need and download all the pdf's. I think 1 day access is about £40 ish but you could pretty much download EVRYTHING in that time.

Failing that you can find workshop manuals in the wiki section of this site that will probably cover what you need. _______________________________________________
