Build up of Cabin pressure

2005 Vauxhall Corsa 1.4 SRI
Car: Vauxhall Corsa
Year: 2005
Variant: 1.4 SRI
Categories: Running Rough, Starting & Power Loss
Please help me!! I have a 55 reg Vauxhall Corsa sri & in the last month i have been experiencing strange air tight pressure or a build up of vibrations that you can’t hear but you can feel in the car. Of course 3 weeks after the warranty has run out!! The pressure is bad when you get in the car & shut the door you can feel your ears tense. It’s almost like your taking off in an airoplane. It seems get worse with the faster you go & between 40mph & 60mph you feel like your head could explode & your ears pop. When you turn the heater on anymore than no.2 then it’s terrible, but there is no noise or whirring sounds??.... I have now taken to driving with my windows open a little & in this weather its not good at all, but still doesn’t make a great deal of difference. This last week I have been driving whilst sitting on a cushion which has helped but not overly much. I have asked many mechanics & they’re all baffled & can’t work out what it could be. All filters are clean, I have tightened my doors so it’s not coming through them...??? I had new tyre’s & brakes fitted on the 18th October but I have tried a different set of wheels but again makes no difference. Iv taken it to a local garage 2day & they think the exhaust is rattling at a higher pace than it should as it enters in to the engine & says its unfixable...???? My local dealer where my warranty work was carried out at are absolutely hopeless & I would never have another Vauxhall again as the service has been so poor. I’m at my last resort as this has now gone on for a month but am reluctant to trade it in. I also not afford to keep taking it different garages for them to charge me to look at it. I have now in total taken it to 4 garages & numerous people are baffled by it. What can i do?..... It’s now starting to distress me. I’d be grateful of any suggestions.

this IS an oddball!!!
this will sound strange , but replace the spark plugs for NEW GENUINE GM plugs.
if that does not help then try this.
have the corsa towed at these speeds with the corsa engine off. try to narrow down the resonations from a running engine. if it is still as bad then it cannot be anything to do with the engine.
although it could be to do with the transmission...
Has the car ever been in an accident? it could also be that it had, and a proper repair ha not been done and the harmonics of the cabin have altered!!!
just a thought... give it a try???
hope this helps

this is the correct answer to this problem. if u go into ur boot and look under the carpet level with the nboot lock approx 4 inches down there will be a white flap with black rubber on it
u will find that this is incorrectly fitted or sumthing is blosking it, refit or remove item infront and u will slove the problem. no need for road test or towing vehicles
good luck
