Omega B Climate Control no heat

[Canker_Canison]

I am looking for a simple fix that won't cost much money...

Some years ago, maybe 2, I flushed the cooling system on my 2.5 V6. The heaters never got to full heat, but were working well enough. Only recently I found out you have to prime the heater matrix after a flush.
In early december I suddenly lost all but a trickle of heat from the blowers. On the previous journey they were fine. The engine temp also failed to reach the normal operating temp.
So working on a possible thermostat issue, I replaced it.
The engine temp is now between 92-95 degrees, but still no heat from the blowers.

I have since flushed the system again & had a play with the bypass valve at the back of the engine. The valve was replaced less than 4 years ago.

During the flush I disconnected the top & bottom heater matrix hose from the valve & put the hose pipe to both ends. The Top hose wouldn't accept any water & the bottom hose just back filled the rest of the cooling system. No water flowed through the matrix. About a week ago I had primed the matrix so a blockage now seems a bit weird.
At this point I fear that the heater matrix is blocked. But I'm hoping someone here can point me to a control valve inside the car. Or a way to unblock the matrix without removing it.

If I get time I'll send my snake cam down the pipe to see what's going on inside, but right now I just need a miracle.

The engine temp is stable, the cooling system is not losing any water & the car runs like ben johnson on speed. So I'm not worried about a head gasket problem.

remove matrix hoses and power washer in to one end of matrix and should clear blockage done this many times

ON TIIC:-

1) not sure on Omega (vomit smiley). What heat you got on pipes of bypass valve? Rovers and saab collapse and dump hot back to the indian

2) try a bycle inner tube full if warer over tank to pressure see if air loc
MAX 15 PSI

3) not sure on omega (vomit, shit, bleed smiley) some cars bleeding you do on a hill

4) some cars have bleed screws see if there is any

5) could be the blender motors sit inside turn heat up and down engine off listen for brrrrrr noises. Start with revirc button fir freferencse


off topic:-

what you charge bloke off street fot iShit MK4. Home button genuine and cioy? Thankssss

Had the hose pipe on there so far, but not tried jet washer. I'll give it a go after I've sent the snake cam down there.

It's fully bled through.

Warm water does come out of the bypass valve. Although I may look at it again.

Vauxhall didn't see the need for bleed valves, retards.

I've already reset the climate control (30 second hold of on/off & Auto buttons) and it made no difference. It made all the right whirring sounds, but didn't fix my problem.

I'd charge you the return postage cost for that fix. But if the screen has been repaired in the last 8 months or so it might not survive being removed. Recent drop in the quality of the LCD ribbons is a nightmare.

Quick update...

Spoke to the dealers, of all people, and actually got some useful information. The matrix is the same on all models. The 2000 facelift matrix is exactly the same as those gone by. So if I have to replace it I'm looking at ?25 off ebay.

But I don't think I'm going to have to replace it. There are two solenoids in the matrix. It could be these that are stopping the water from entering the matrix. Something is getting through as the car does eventually get warm inside. So I'm planning in bleeding ith again once it's up to temp, but I'll turn the ignition on so the solenoids should open.
I'm also going to add a T piece to the top matrix hose to make future work easier.

Nice not sutee hie easy to do can you remove the middle out of solnoids fr tedting pupises?

as gir bleed screw on maxtrix good idea not sure in length space size etc etc go to a scrao yard find a oug 296 or even a pug 206 with air con. MAKE SURE IT HAS NO GAS IN IT, chop off the bulkhead the floating ac filler take to metal eirk dhop fir them to alky weld it on, you got a dinkey fick to blled with screwdriver

F-me Meaty! What were you on last night? That's almost as hard to understand as one of my sisters text messages.

With luck I'll get a few hours to play with it tomorrow. Not sure my arms ready for it yet though. Bruised the radius in my left arm the last time I attacked those pipes.

Ask gastonj he understands iShit speak

remove the middle out the solenoid for testing

[Canker_Canison]

I've got to get to them first.

Fitted the T-piece on saturday. Need to send the snake cam up that pipe. Still getting nowhere. Currently thinking it's an electrical problem with the solenoids.
I'll be using the cam to hunt down the pesky buggers & see if I can either remove them or at least disconnect & run 12v through them.

sorry lost intrest now

sorry lost intrest now

I'm getting there myself.

The vacuum valve you listed twice is not the problem. The side with two pipes is the feed & return for the matrix. The top pipe is where I put the T-piece. This has confirmed that no water is getting to the matrix (other than a very slow trickle). The valve itself is fine since it blew the blot blocking the T-piece extension pipe out the other day. Which then emptied my coolant in less than 15 seconds .

According to the dealers there are solenoids attached to the matrix unit. I'm taking it that these close when the air con is on so no hot air reaches the cabin through the matrix.

When I get time to send the camera in there I'll see if I can grab some stills & post them up here.

Quick update.

I gave in.

Sold car to a friend who want's to put the engine & running gear into a chav'd out corsa & make it rear wheel drive.

I now have a depressingly slow Focus C-MAX.

Cool theres an INFERIOR forum fir chav mobiles. Barryboys.couk be sure to hyper link it in this thread when done.

your weird friend MUST MUST seam weld as much as possable and add as many gussestz as possable.
