Question about 2004 Toyota RAV4
Oil and engine magament light both keep coming on both amber colour any one have any idears of what's wrong also my blowers and heating have stopped working used to work if I went over a bump in road but stopped altogether now
Is it a diesel? check oil level, if it is high (over full). The DPF filter is blocked, when it tries to regenerate it dumps more fuel into system, if it can't regen the extra fuel goes into the sump, hence the lights. Dealer might be able to force regen, if not it's an expensive replace filter. Blower problem sounds like a bad electrical connection or possible motor fault. test motor first, by direct feed a fused battery link and work your way back to the switch.

SOURCE: engine management light turn on
The technically proper diagnostic procedure would be to have the car's computer scanned and the readings interpreted for errors. The error codes would determine the "probable" defects.
To my knowledge, any sensor failure or reading/condition error with respect to the engine would trigger the engine management light. Most notably common to Toyota Camrys are the O2 sensors which would require original Toyota parts (for compatibility with the onboard computer) and not aftermarket such as Bosch. Scan readings would indicate error code PP107 or something like it.
In some cases, it could be part of the throttle assembly (throttle position sensor) and/or sticking parts which of course cleaning solve.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Check the resistor between the wiring and the blower under you dashboard. It is a small gadget. Not an electronic resistor as in TV resistors.I don't know what kind of noise . Is it a clicking noise a whirling noise ? what kind ? If this helps please vote.

Hi, I can tell you that I was having a simular problem with my 2001 Chevy Silverado. The check engine light would come on and I lost both the speedometer and odometer. I also lost gas gauge, and oil pressure gauge.I would hit a bump and they would start working, but light would stay on. I bought the obd-2 meter to read codes and erase them so the light went off. This continued for 8 months. Finally, I started moving wires around under dash when gauges stopped and they would come on and off? Took me right to the circuit board on the ignition switch. I mean I tried everything possable to solve this and told a G.M. mechanic. He said I was right that it would be the switch and that most of you're wires that go to gauges and speedometer come from the ignition switch. I changed it and it has been fine since. You might try what I did see if you can do this while driving, i don't no, but if so be carful on the road. You may need to take it in also.There is something loose a ground wire or hot doing this. I would bet it is in the ignition switch. Best of luck,
