LCM Replacement

[89VERT]

My LCM is not allowing me to put on high beams .Does it also control the heating and cooling system as well ? Is this a rather simple job to replace? It sure looks like it . Or is it better to have the dealer do it in case of any electrical gremlins ?

ask Bob6364, he just did this.

but no the lcm does not control the heating at all.

Do a search...LCM is easy to replace....300 dollar parts cost tho. Cheaper to replace the relay in the unit.

sounds like you have 2 modules going bad at the same time....can you hear the doors opening and closing in the dash but nothing changes in the passenger comparment?

What happens is that when you want to change the airflow from floor to vent etc. , it does not always change right away, but it eventually does . Sometimes this will take a minute or so.
