Hi,
I wonder if you can help me. The heating in my car is almost gone. Noticed it about two winters ago, but now it's hardly possible to sit in the car;) Oh, please apologise for a rather longish post, but I want to give as much details as possible.
Here's the whole story:
I went over to Poland for christmas and so I took my omega to my old man's mate who has a garage (deals only with Vauxhalls and Opels). He's done the usual, fixed some bits and bobs, then he found that my head gaskets were gone so he needed to take half of the engine out etc. I told him about this problem with my heating and that he could perhaps replace the ol' rusty heat exchanger (matrix you call it?). All in all he didn't have time to do that but as we went to check the heating it was blowing super hot air just after he put the engine back together...yeah, for a day before it came back to be barely warm.
Then I went to a car wash and after that all fans went crazy and blew at their max speed even after I switched the engine off and took the key out. Turned out that the car wash flooded my passenger's side and water was leaking for a good hour (as the fans were blowing slower and slower). Few days after that little hickup I noticed that the air-con is not doing anything when I press the ECO button i.e. revs don't go up or down as they used to. Every few engine starts the fans don't switch on at all only until I do the climate control reset (AUTO+OFF). Everytime I switch off the engine I get (--) where the climate temperature should be.
In a nutshell:
1. No difference in air temperature between 19C and HI setting
2. Getting (--) upon switching off the engine - was told that it was because of the difference in the temperature sensor readings and it was supposedly rectified.
3. A lot of water got into my car through under the glovebox (enough to form a puddle) after visiting a car wash and shorted the fan control and set it all to max setting.
The next two issues started happening after the flood
3. Aircon does not respond to ECO button
4. Fans fail to start ocassionaly until Climate Control is reset with AUTO+OFF
5. Once it did not respond to changing the air flow - got stuck on windscreen 'de-mist' until reset
6. Still getting the (--)
1.Replaced radiator in November 2011 (leaked)
2.Head gaskets, oil cooler, hydraulic valve thingies, throttle regenerated, everything sealed properly, new cam belt (decided to leave old pullies), 5w40 full synthetic, Climate Control 'backlight', pollen filter, air filter, oil filter in December 2011
3.Thermostat, water pump, cam belt and all there is to it in December 2010
4.HGV or HBV? in spring 2009 (was leaking when set to HI)
The temp. dial is holding still no matter what (just drove over 1.2k miles), engine running perfectly fine and smooth, did not take any oil since the head gaskets were done, coolant level is steady (which was not the case before the job).
So...what the hell is going on with my climate control god damn it??
I would appreciate any advice but, if at all possible, I would like to perhaps meet one of the local omega gurus to have this looked at. Has anyone got a tech2 in or around Nottingham and would not mind checking this anomaly?
The car is a 1998 3.0 LHD with manual transmission.
Please help...please?
