Re: check gearbox light, car drives sluggish,heater cuts...
You have a bad gearbox position sensor located on the transmission. When the transmission computer sees the fault in that sensor it goes into a protective mode in your car starts out in second gear that's why it is sluggish. This is a very common failure on that car. The heater issue is not related.

Check engine and check gearbox on an automatic...neutral safety switch is going out. First couple starts like that and it seems like it's in limp home mode...it is. A few more starts and it will reset itself. Mine did so reliably at the 5th restart until I changed it.
Get a used on if you can, they are not really rebuildable reliably. Pain to change, it's under the battery tray and miserable to get to.
You need a new neutral safety switch. The car does not know what gear it is in so it goes into safe mode and sets off in third gear. There about £150 new but i got one from the scrap yard for a fiver. There is a guide on one website that shows you how recondition the switch but can't remember which one.
is it an auto? if its a manual then its either your clutch, or gearbox does it make a crunching sound when going into gear? if it does then it's the clutch gone. careful driving it as you might damage the box
Hello. I had the same problem when the Check Gearbox light came on, it would be very sluggish. It turned out to be a small sensor in the transmission that lets the car know what gear it is in. It started to go out slowly and only sometimes would send the information.
Hi guys,obviously this could be any number of problems,but the most common ones to cause this is a dirty throttle intake housing,usually a good clean up rectifys this,also check the small vacum hoses for any splits or perishing as this also can cause this problem,hope this helps you's out,Bill.
Sounds like the recirculation valve (aka diverter valve) is failing. A lot of turbo cars that have them end up with failures from them, since they're usually cheaply made from plastic, and the diaphragms inside don't hold up over time.
What the valve does is, when you shift, there is a backsurge of boost air that hits the closed throttle plate. The diverter valve (DV) opens and dumps the air back into the intake piping. It's kept closed during acceleration by spring and manifold pressure. When you shift, the pressure drops on the backside of the valve and it opens, venting the excess boost air. If your valve is failing, just the pressure of boost in the intake piping could be pushing it open, causing the acceleration to slow. I'd look into a replacement diverter/recirculation valve.
