abs error and tractioncontrole is solved there was brown gunk on the abs ring so the magnet couldn't make any contact. The heater that only blow cold air was the dccv I toke the cable off and there was hot air so I going to replace it now. The parking break warning light and the power steering that did go off are fix now the problem was the battary. I charge it and now it's fine. Thnx all

Glad to hear you’ve got the other faults cleared up. You are to be commended for your perseverance. It’s interesting that you had three faults in play at the same time. Here’s to systematic troubleshooting, as sometimes there’s no single magic fix.

One slight hitch with the lack of heat, though. The two internal valves in the DCCV are spring-loaded to the open position. The logic is to allow max heat in case of an electrical failure. This makes sure the defroster can clear the windshield as a safety precaution.

You removed the DCCV connector and had full heat. That means the DCCV itself is probably fine, but is getting an erroneous command to the full closed (cold) position. Remember power to the DCCV = cold, no power = hot. You’ve got to determine why the DCCV is getting the cold command (power to the plug) when it shouldn’t.

Have you played with manual mode on the control panel? Bump up the temperature selection until HI is displayed. This bypasses most of the automatic inputs.

Edit: If you need to temporarily drive the car until you can fix the heater, you can safely do so with the DCCV plug removed. You'll have LOTS of heat, though. Manually turn down the fan speed as needed and be prepared to open a window or two.
